Abstract: A fuel cell system and a fuel cell vehicle that prevent deformation of a fuel cell case when an external force is applied are provided. A fuel cell system includes a fuel cell case configured to contain a fuel cell; and an auxiliary device fixed to a side surface of the fuel cell case. The auxiliary device includes: a first support part fixed to the fuel cell case; a second support part fixed to the fuel cell case at a position spaced apart from the first support part; and a main body part supported by the first support part and the second support part spaced apart from the fuel cell case. The first support part is broken before the second support part is broken when an external force is applied to the main body part in a direction approaching the fuel cell case.

Abstract: Disclosed is a method for producing an electrode material for fuel cells, which electrode material has excellent electrochemical catalytic activity and uses a non-carbon conductive oxide carrier having high durability. Specifically disclosed is a method for producing an electrode material for fuel cells, which comprises the following steps. (1) A step wherein carriers mainly composed of tin oxide are dispersed in a solution containing a noble metal colloid, and the noble metal colloid is reduced so that the carriers are loaded with noble metal particles (2) A step wherein the carriers loaded with the noble metal particles are separated from the liquid and dried (3) A step wherein the dried carriers loaded with the noble metal particles are subjected to a heat treatment at a temperature of not less than 80° C. but not more than 250° C. in the presence of a reducing gas.
