Engineered Catalyst Support (ECS)

Pajarito Powder manufactures advanced catalyst support materials for use in fuel cell and (in some) electrolyzer applications. Using proprietary methods and materials, Pajarito Powder products improve fuel cell performance, extend working life and reduce the cost of fuel cells for the most demanding applications, including heavy-duty fuel cell vehicle applications. ECS is composed of inexpensive, widely available materials, manufactured economically at scale using the patented VariPore™ process. ECS materials enable highly specific platinum (and platinum alloy) catalyst performance (activity) while combining high resistance to both carbon corrosion (durability) and platinum dispersion (stability). Superior PGM adhesion is a fundamental property of these materials, while offering substantial improvements in overall catalyst performance.

Complete Catalyst Solutions:  PGM Catalysts utilizing ECS

Pajarito Powder designs, develops and manufactures advanced catalysts utilizing our own Engineered Catalyst Supports™ with variable intrinsic characteristics that are tailored to specific customer requirements, such as highly graphitized or mesoporous and meta—doped materials with medium levels of graphaticity. Complete catalyst solutions incorporate advancements in PGM deposition, utilizing the intrinsic capabilities of the ECS material to improve durability and performance of the catalyst.

Engineered Electrolyzer Catalysts™ (EEC)

Pajarito Powder develops and manufactures electrolyzer catalysts for a range of chemistries and applications. PEM materials for anode feature Iridium-reducing methods that yield high surface areas and lower PGM requirements. PEM cathode materials utilize PGM alloys on Pajarito Powder’s proprietary Engineered Catalyst Support, for superior PGM utilization and durability.  AEM materials in development include low-cost, PGM-lite materials such as PbRuOx for anode and completely PGM-free solutions like NiFeOx and LaSrCo. Similarly, on cathode, nickel alloys on ECS provide highly durable catalysts with a PGM-free solution. 

Materials under development at Pajarito Powder offer the potential for lower capital (CapEX) and operating (OpEx) costs for electrolyzers, critical to broad deployment of clean, on-demand and on-site hydrogen production.

Precious-Metal-Free™ (PMF) Catalysts

Pajarito Powder’s world-leading commercial precious-metal-free catalysts provide a low-cost solution for low and moderate power density applications such as stationary or back-up power, CHP and waste-water treatment. PMF materials also offer the potential, given component, stack and system optimization- for the replacement of precious metals in fuel cell catalysts over the long term. Manufactured with the proprietary VariPore™ process, Pajarito Powder PMF catalysts achieve unprecedented activity, stability, and reasonable durability under real-world operating conditions, all at material and production costs that are dramatically lower than platinum-based catalysts.
