The Pajarito Powder team brings extensive experience from both fuel cell startups and the industry as a whole, from theoretical and practical applications in research, and finally from manufacturing and business development.  Pajarito Powder is poised for success, given its world-class Technical Advisory Board, experienced Board of Managers, a Chairman & CEO with a successful fuel cell exit and a CTO & President with extensive catalyst engineering experience.

All contribute to the effort to produce advanced Engineered Catalyst Supports (ECSs) for Fuel Cell Electric Vehicles (FCEVs), as well as Precious-Metal Free (PMF) catalysts for other fuel cell applications, at a fraction of the historical cost while optimizing performance. Pajarito Powder’s  patented VariPore™  process is readily-scaled for high-volume manufacturing – the condition ultimately necessary for cost-effective, widespread fuel cell adoption.

Board of Managers


Thomas J. Stephenson,

Board Chairman




Dr. J. Byron McCormick

Dr. McCormick is widely regarded as one of the ‘founding fathers’ of modern mobile hydrogen fuel cells.  He began his career in the Electronics Division at Los Alamos National Laboratory, where he worked with many talented and mission-driven scientists on fuel cell technology. Dr. McCormick’s leap of considering fuel cells, which had played in a role in getting a rocket to the moon, for use in automobiles, was borne of a desire to avoid another energy crisis like that of the late 1970’s. Dr. McCormick founded the Department of Energy’s Fuel Cells for Transportation program, where research in PEM fuel cell technology for future automotive applications was developed and funded.

Dr. McCormick worked at General Motors for three decades, where he formed and was Managing Director of Delco Propulsion Systems which developed and commercialized the integrated electric propulsion systems, subsystems and componentry for GM’s EV1 and S10 electric vehicles.  Subsequently forming and leading GM’s Global Alternative Propulsion Systems organization which was responsible for all aspects of GM’s hydrogen and fuel cell development activities worldwide, Dr. McCormick, transitioned these activities into the main operating divisions of the Corporation in preparation for the upcoming launch of GM’s hydrogen fuel cell vehicles. Dr. McCormick retired from GM in 2008 and consults for various governments and corporations globally on sustainable energy initiatives through Prepared Minds International.


Paul Short

Mr. Short was a co-founder of Pajarito Powder, along with Mr. Stephenson. Mr. Short holds a BS and an MS in Electrical Engineering from New Mexico State University, and held positions with both NMSU’s Physical Science Laboratory and Honeywell as a Principal Engineer. Later he founded InnovASIC, a design services company that developed integrated circuits for other companies. Mr. Short later evolved InnovASIC from a services firm to a semiconductor producer that designs, manufactures, and sells integrated circuits, earning over $5 million in revenue during a period of industry contraction. He was also the founder of Metaphor Computing and Chief Operating Officer of Altela, a water treatment equipment manufacturer. At Altela, he led the team that designed, manufactured, installed and tested the next generation product, generating  $1.6M in revenue in one year.


Technical Advisory Board

Pajarito Powder has a world-class Technical Advisory Board that drives the company’s technology and product to be of the highest performance and durability, while meeting the price and manufacturability targets required by industry.

Dr. Scott Calabrese Barton

Calabrese Barton is an Associate Professor of Chemical Engineering at Michigan State University. His research group studies new electrocatalysts, materials, and electrode design for both fuel cells and chemical conversion. Transition metal electrocatalysts are studied for fuel cell and electrochemical conversion applications. Bioconversion involving enzyme electrocatalysts are also studied as a means of producing value-added chemicals from renewable resources. To this end, regeneration of enzyme cofactors and high-surface Carbon materials are developed for immobilization of enzymes, catalysts, and cofactors. Throughout this work, mathematical models promote understanding of electrochemical kinetics and transport, leading to tools for analysis and optimization of novel electrode architectures. Dr. Calabrese Barton received his Ph.D. in Chemical Engineering from Columbia University in 1999, after studying aerospace engineering at Notre Dame and MIT. He is the recipient of a prestigious CAREER award from the National Science Foundation and a Petroleum Research Fund award from the American Chemical Society.
