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 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 (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.

Pt / Pt Alloys in Engineered Catalyst Support

Pajarito Powder designs, develops and manufactures advanced 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.

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 long-term replacement of precious metals in fuel cell catalysts. 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.

Engineered Electrolyzer Catalysts (EEC)

Pajarito Powder recently began expanding the use of its VariPore™ process and extensive knowledge of low-cost catalyst materials by
developing new formulations for electrolyzer applications.

While our research, supported by a cooperative agreement from the U.S. Department of Energy ARPA-E (Award DE-AR0000688) is still in its early stages, evaluation samples are available to select customers and partners. The inexpensive catalyst materials under development at Pajarito Powder offer the potential for lower capital and operating costs for electrolyzers, critical to broad deployment of clean, on-demand and on-site hydrogen production.
