Pajarito Powder to Show a Strong Presence at North American Catalysis Society Conference

June 5th, 2017 • Posted by PPC • Permalink

The North American Catalysis Society hosts its 25th biennial conference at the Hyatt Convention Center in Denver, Colorado from June 4th -9th. The conference is the premier scientific event in the field of catalysis research and development in 2017.

Pajarito Powder is center stage at the six-day event, as a sponsor, co-chairing two sessions at the conference, displaying papers and posters demonstrating the frontier of fuel cell and electrolyzer catalysis research, and supporting social media coverage.

Dr. Barr Zulevi, President and Chief Technology Officer at Pajarito Powder, is co-chairing two of the Catalysts for Fuel Cells sessions and commented “I’m excited and privileged to facilitate these sessions since NAM25 is the premier catalyst conference in North America and the session presentations will be excellent.” Links to the sessions co-chaired by Dr. Zulevi, as well as the research presented in each session, are found via the links below:

Sessions Co-chaired by Dr. Zulevi:

Several of Pajarito Powder’s engineers will present research at the conference. The topics presented include “Economical MOF-Based Precious-Metal Free Oxygen Reduction Reaction Catalysts, Durable Engineered Carbon Supports, and Controlled Structure Manufacturing of Porous Carbons.” Abstracts for the research presented by the Pajarito Powder team can be found on the conference website at the locations, below:

In addition to being a sponsor of NAM25, its presence on social media will be facilitated and supported by Pajarito Powder. “Social media presence is a great opportunity to expand reach to members and increase contribution toward catalysis research in North America,” commented Thomas J. Stephenson, CEO and Chairman, about Pajarito Powder’s social media support. “We’ll acknowledge sponsors, presenters, and contributors on Twitter, further promoting discussion around catalyst development.”

Please follow developments at the conference as they unfold via Twitter through @NAmCatSoc and #NAM25.

Highly stable PGM-free cathode catalyst paper published

August 4th, 2016 • Posted by Pajarito Powder • Permalink

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:
