Lessons Learned from Phosphoric Acid Electrolyte Fuel Cell Development Pertinent to PEMFCs

Abstract

The recent high level of activity on proton exchange membrane (PEM) fuel cells has brought into the fuel cell community many new participants who are unaware of the vast phosphoric acid (PAFC) research results that are available and pertinent to PEM fuel cells. This report provides a summary of some of the PAFC information related to cathode catalyst activity, cathode performance decay, and electrolyte migration.
