Title:
MEMBRANE ELECTRODE ASSEMBLY FOR SOLID POLYMER FUEL CELL
Document Type and Number:
WIPO Patent Application WO/2006/070635
Kind Code:
A1
Abstract:
This invention solves environmental problems of solid polymer fuel cells by suppressing formation of partial oxides such as formaldehyde by electrochemical oxidation of the liquid fuel. Specifically disclosed is a membrane electrode assembly for solid polymer fuel cells whose most significant feature is in that a byproduct decomposition catalyst containing activated carbon as a constituent is contained in the catalyst layer of at least one of the anode and cathode for decomposing the partial oxides.
