| 1. A method for bonding a separator and an electrolyte layer of a fuel cell assembly, wherein said electrolyte layer comprises
a frame and an electrolyte retained in said frame, the method comprising:
depositing a metallic material on a peripheral portion of one of said frame and said separator;
disposing said frame and said separator such that said frame and said separator contact each other with said metallic material
disposed therebetween; and
irradiating radiation energy onto said metallic material through said frame or said separator to thereby form a eutectic of
said metallic material and the other of said frame and said separator;
wherein said separator and said frame are each made of a substrate consisting of an inorganic material;
wherein said frame or said separator through which said radiation energy passes is sufficiently transparent to said radiation
energy to enable said eutectic to be formed.
