Title:
AIR-BREATHING DIRECT METHANOL FUEL CELL WITH METAL FOAM CURRENT COLLECTORS
Document Type and Number:
WIPO Patent Application WO2002059998
Kind Code:
A3
Abstract:
A method and apparatus for generating electricity by direct oxidation of methanol is disclosed. Said apparatus is disposed in a wall of an enclosure suitable for containing liquid fuel. Methanol is passed through a porous anode current collector to contact the anode electrode of a polymer electrolyte membrane fuel cell, an oxidant is passed at atmospheric pressure through a porous cathode current collector which acts as an air diffuser to contact the cathode electrode and the methanol is directly oxidized, producing water which is removed through the cathode current collector, carbon dioxide and electricity.
