Title:
PLYMER SOLID ELECTROLYTE FUEL CELL
Document Type and Number:
Japanese Patent JPH06103992
Kind Code:
A
Abstract:
PURPOSE: To prevent decrease of cell voltage due to crossover of hydrogen gas and oxygen gas in a fuel cell and at the same time make an economical hydrocarbon type ion exchange membrane with small inner resistance usable. CONSTITUTION: A catalytic layer 7 electrically insulated from a cathode 2 and an anode 4 is formed in an ion exchange membrane 3. Hydrogen gas and oxygen gas crossing over in the ion exchange membrane are reacted each other by the catalytic layer 7 and moved to an opposed pole to suppress decrease of cell voltage and further radicals by which the ion exchange membrane is easily deteriorated are decomposed by the catalytic layer 7. Moreover, the ion exchange membrane 23 is made to be a single membrane and a catalyst metal 26 which is not electrically insulated and a catalyst metal 29 which is electrically insulated may be supported in the cathode 24.
