Title:
MEMBRANE ELECTRODE UNIT FOR A SELF-HUMIDIFYING FUEL CELL, METHOD FOR PRODUCING SAID MEMBRANE ELECTRODE UNIT AND FUEL CELL BATTERY
Document Type and Number:
WIPO Patent Application WO2000063989
Kind Code:
A3
Abstract:
The invention relates to a membrane electrode unit for a self-humidifying fuel cell and to a method for producing the same. The invention also relates to a self-humidifying fuel cell battery. The membrane electrode unit comprises a membrane electrolyte into which at least one catalyst layer is laminated so that water can be produced specifically inside the membrane by recombination of the reaction gases H2 and O2.
