Pajarito Powder Makes Inaugural Appearance at HFC 2017 in Vancouver

June 12th, 2017 • Posted by PPCPermalink

The biennial Hydrogen and fuel cells summit was held this past week in Vancouver, Canada, with the intention of building awareness around the economic, environmental and social benefits of hydrogen and fuel cells.

The title for this year’s summit was: The Hydrogen and Fuel Cell Renewal: Clean Cars, Clean Power, Clean Solutions, and Pajarito Powder’s Chairman and CEO Thomas J. Stephenson took the opportunity to describe the unique approach taken by engineers at Pajarito Powder during the conference’s open presentation session. “Our PEM catalysts have the ability to increase performance and dramatically lower the costs, by substantially reducing the amount of platinum,” commented Mr. Stephenson during his presentation. “We do this by focusing on the forgotten partner of the catalyst system, the carbon support material”.

Dr. Yun Li, Pajarito Powder’s China Market Liaison, also attended the conference and drew attention to Pajarito Powder’s advances in PEM Fuel Cell research, as well as the company’s new initiatives in China. “Our new contacts wish to stay updated on Pajarito Powder’s progress, and even asked for recommendations for MEA companies,” recalled Dr. Yun after the conference.

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.
