ELECTRODE FOR FUEL BATTERY, CELL FOR FUEL BATTERY, AND STACK FOR FUEL BATTERY

摘要

This invention provides an electrode for a fuel battery, which can improve both current collection properties and oxidizing gas and/or fuel feedability by allowing produced water to be more easily removed, and a cell for a fuel battery, and a stack for a fuel battery. The electrode for a fuel battery comprises a net material (51, 52), a microporous layer (MPL) (51b, 52b) formed integrally on one side of the net material (21, 22), and a catalyst layer (51c, 52c) formed integrally on one side of the net material (21, 22) closer to the surface. The net material (51, 52) is in a plate form and has an electrically conductive material plate (53) on its other side. The microporous layer (51b, 52b) has a number of interconnected micropores and, at the same time, is electrically conductive and repellent to water. The net material (51, 52) has a number of interconnected voids and, at the same time, is electrically conductive, and each void, together with the plate (53), constitutes an air chamber or a fuel chamber. The catalyst layer (51c, 52c) abuts against an electrolyte membrane (54).
