Highly stable PGM-free cathode catalyst paper published

Members of the Pajarito Powder technical team and professors from the University of New Mexico contributed to an article published in the Journal of Power Sources.

“Highly stable precious metal free cathode catalyst for fuel cell application,”  will appear in the September issue of the academic publication.

The highlights of the article touch on the highly stable PGM-free synthesized cathode catalysts and how  their morphology influences activity and stability.

The abstract details the nature of the findings:

“A platinum group metal-free (PGM-free) oxygen reduction reaction (ORR) catalyst engineered for stability has been synthesized using the sacrificial support method (SSM). This catalyst was comprehensively characterized by physiochemical analyses and tested for performance and durability in fuel cell membrane electrode assemblies (MEAs). This catalyst, belonging to the family of Fe-N-C materials, is easily scalable and can be manufactured in batches up to 200 g. The fuel cell durability tests were performed in a single cell configuration at realistic operating conditions of 0.65 V, 1.25 atmgauge air, and 90% RH for 100 h. In-depth characterization of surface chemistry and morphology of the catalyst layer before and after durability tests were performed. The failure modes of the PGM-free electrodes were derived from structure-to-property correlations. It is suggested that under constant voltage operation, the performance loss results from degradation of the electrode pore structure, while under carbon corrosion accelerated test protocols the failure mode is catalyst corrosion.”

Authors of the article include Alexey Serov, Plamen Atanasov, members of Pajarito Powder’s Technical Advisory Board, Michael J. Workmana, Kateryna Artyushkova, as well as Pajarito Powder CEO & Chairman, Tom Stephenson, CTO & President, Barr Halevi, and contributing staff members Geoffrey McCool, Sam McKinney, & Henry Romero.

The article is currently available, for 30 days, for free at the Journal of Power Sources:

 

Pajarito Powder to Exhibit at Hannover Messe

Pajarito Powder, LLC announced it is part of the largest-ever U.S. delegation to Hannover Messe, the world’s foremost trade fair for industrial technology, taking place April 25-29, in Hannover, Germany. For the first time in the fair’s history the United States will be a Partner Country.

Pajarito Powder invites its customers and partners to meet at the HYDROGEN+ FUEL CELL+BATTERIES Group Exhibit, in Hall 27, C66 at booth D31. A map of the hall is available here.

Pajarito Powder engineers and manufactures catalysts and advanced Engineered Carbon Supports (ECS), dramatically reducing or eliminating the need for precious metals in catalysts. The Pajarito Powder team will be on-site, hosting meetings with customers and partners in the fuel cell industry. The primary focus is on customers and partners attending the event, which begins on April 25 and runs until April 29.

Pajarito Powder will present at the Technical Forum, Tuesday April 26, at 13:20 on

“Engineered Carbon Supports for low precious-metal-content catalysts,” as well as at the Public Forum, on Thursday April 28, at 14:20, on the “True value proposition of low-platinum catalysts.”

Pajarito Powder is exhibiting two flagship products, PHC-3000, the company’s new Engineered Carbon Support (ECS) – being launched at the show – for ultra-low platinum catalysts designed for high-power applications where durability and performance are uncompromising, and NPC-2000, a precious-metal-free catalyst that substantially reduces the cost of catalysts for lower power applications. .

Chairman and CEO Thomas J. Stephenson stated, “The Hannover Messe is the premier industrial show in the world and provides Pajarito Powder with an enviable opportunity to showcase our innovative products to not only our European customers, but the entire world.”

This is the third year that Pajarito Powder exhibits at the Hannover Messe, thanks in part to assistance from a United States Trade Administration program, managed by the New Mexico Economic Development Department, that partially offsets the cost of trade shows for advanced technology New Mexico companies.

Pajarito Powder to Exhibit at Fuel Cell Expo

March 2 – Pajarito Powder invites customers and partners to meet at the 12th International Hydrogen & Fuel Cell Expo, or “Fuel Cell Expo 2016,” hosted at Tokyo Big Site, at booth E33-35, and part of World Smart Energy Week, in Tokyo, Japan.

Pajarito Powder engineers and manufactures catalysts and advanced Engineered Carbon Supports (ECS), dramatically reducing or eliminating the need for precious metals in catalysts. The Pajarito Powder team will be on-site, hosting meetings with customers and partners in the fuel cell industry. The primary focus is on customers and partners attending the event, which begins on March 2 and runs until March 4.

Pajarito Powder is exhibiting two flagship products, NPC-2000, a precious-metal-free catalyst that substantially reduces the cost of catalysts for lower power applications and PHC-3000, the company’s new Engineered Carbon Support (ECS) for ultra-low platinum catalysts designed for high-power applications where durability and performance are uncompromising.

Chairman and CEO Thomas J. Stephenson started, “Fuel Cell Expo is a very important event for Pajarito Powder, one that provides us with exceptional opportunities to meet with many of our Asia customers and partners in one location over a compact time-frame.”

This is the fourth year that Pajarito Powder attends Fuel Cell Expo, thanks in part to assistance from a United States Trade Administration program, managed by the New Mexico Economic Development Department, that partially offsets the cost of trade shows for advanced technology New Mexico companies.

Pajarito Powder, LLC Announces Precious-Metal-Free Fuel Cell Catalysts Licensing Arrangement with Los Alamos National Laboratory

Pajarito Powder, LLC (PPC), manufacturer of advanced Engineered Carbon Supports and catalysts Fuel Cells, has entered into a licensing arrangement with Los Alamos National Laboratory (Los Alamos) to transfer, evaluate and commercialize the world’s leading precious-metal-free fuel cell catalysts developed by Piotr Zelenay and Hoon Taek Chung of Materials Synthesis and Integrated Devices at Los Alamos. “This licensing arrangement with Los Alamos nicely enhances Pajarito Powder’s intellectual property with regard to platinum-free catalyst development, our core focus”, said Thomas J. Stephenson, PPC’s CEO and Chairman. Platinum has historically represented a high-cost component of fuel cell technology, thereby preventing wide-scale adoption. Incremental improvements in the activity and durability of platinum-free engineered carbon supports are contributing to the global maturation of the industry, and promoting development of manufacturing capacity in the United States. “These patents lay the groundwork for future development of platinum-free catalysts,” stated Zelenay who is a Los Alamos fellow and contributor to the patent work. Zelenay has been at the forefront of developing precious-metal-free fuel cell catalyst. His original work is published in the scholarly magazine Science, “High-Performance Electrocatalysts for Oxygen Reduction Derived from Polyaniline, Iron, and Cobalt”.

Pajarito Powder Welcomes Dr. Jean-Pol Dodelet to its Technical Advisory Board

Pajarito Powder is pleased to announce the addition of Dr. Jean-Pol Dodelet to its Technical Advisory Board. Dr. Dodelet is Professor of Physical Chemistry at L’Institut National de la Recherche Scientifique (INRS) Canada. He received his Ph.D. in Physical Chemistry in 1969 from L’Université Catholique de Louvain (Belgium). At INRS in the 1990s he became interested in non-noble metal electrocatalysts. In the last several years, Dr. Dodelet collaborated with General Motors as Industrial Research Chair in electrocatalysis, sponsored by General Motors of Canada and the Natural Sciences and Engineering Research Council of Canada.

“Dr. Dodelet brings significant experience with non-noble metal electrocatalysts and electrocatalysis, which complements PPC’s technical advisory group’s knowledge base. We look forward to his input as we continue developing our work manufacturing advanced engineered carbon supports for fuel cell catalysts,” said Thomas J. Stephenson, Pajarito Powder, LLC’s, CEO & Chairman.
