Separator einer Protonenaustausch-Brennstoffzelle und Verfahren zu dessen Herstellung

摘要

A method of manufacturing the separator of the proton exchange fuel cell. In a cell stack of a proton exchange fuel cell, the cell stack composed by laminating a plurality of unit cells and a plurality of separators, each of the unit cells composed of an anode electrode, a cathode electrode and a solid polymer electrolytic membrane arranged between the anode and cathode electrodes, each of the separators arranged between the unit cells, respectively, the method of manufacturing the separator of the proton exchange fuel cell, includes the steps of, preparing step for preparing raw material for the separator, the raw material composed of alloy material including light metal, such as aluminum or magnesium, as a main component, and forming step for forming the separator from the raw material by die casting.
