U.S. Department of Energy Polymer Electrolyte Membrane Fuel Cell Catalyst Development Activities

The U.S. Department of Energy is supporting the research, development, and deployment of all types of fuel cells for transportation, material handling, portable power, back-up power, stationary power, and combined heat and power applications. A major focus of this support is polymer electrolyte membrane fuel cells. Key issues inhibiting their widespread penetration and commercialization of fuel cells are performance, durability, and cost and a key component is electrode technology including supports and catalysts. The approaches to improvement in electrode technology include alloys, core/shell structures, thin continuous catalyst films, non-precious metal catalysts, and alternative supports. Major progress has been realized recently. This paper provides an overview of DOE-funded advances and status.
