    摘要: An electrode support for fuel cells, the electrode support being made of a porous material having a Ni phase of Ni or NiO and an inorganic skeletal material phase, wherein an oxidation/reduction expansion-suppressing metal M of at least one selected from the group consisting of Fe, Co and Mn is solidly dissolved in the Ni phase or is biasedly distributed on the grain boundaries between the Ni phase and the inorganic skeletal material phase. The electrode support has its volume very little expanded or contracted even in an environment in which it is exposed to the reducing atmosphere and the oxidizing atmosphere alternately. The fuel cell having the fuel electrode, electrolyte layer and oxygen electrode formed on the electrode support effectively prevents the occurrence of cracks or exfoliation caused by expansion and the like when the reduction/oxidation cycle is repeated accompanying the generation of electricity and stop of generation, and maintains reliability very excellently over extended periods of time.
