Title: CELL FOR SOLID POLYMER FUEL CELL, AND SOLID POLYMER FUEL CELL STACK
Abstract:
A cell 10 for a solid polymer fuel cell and equipped with an anode-side cell constituent member 11 and a cathode-side cell constituent member 12, wherein: the anode-side cell constituent member 11 comprises a ferritic stainless steel material, and the cathode-side cell constituent member 12 comprises a stainless steel material; the ferritic stainless steel material which constitutes the anode-side cell constituent member 11 has a chemical composition in which the Sn content is 0.02-2.50%, by mass%, and has a precipitate therein which contains a finely dispersed and precipitated M2B boride; part of the precipitate projects from the surface of the ferritic stainless steel material; and the stainless steel material constituting the cathode-side cell constituent member 12 has a chemical composition in which the Sn content is less than 0.02%, by mass%.
