Claim:
1. A fuel cell constituted of: a membrane electrode assembly comprising a polyelectrolyte membrane, electrode layers placed on both the sides of the electrolyte membrane, and gas diffusion layers placed on the side opposite to the electrolyte membrane of the electrode layers; a gas sealing material placed surrounding the membrane electrode assembly; and separators sandwiching the foregoing, wherein the fuel cell comprises a peroxide decomposition catalyst immobilized on a support; wherein the immobilized peroxide decomposition catalyst comprises cerium; wherein the support is zirconium phosphate having a three-dimensional network, a clay mineral having an interlayer structure, or zirconium phosphate having an interlayer structure; wherein the immobilized peroxide decomposition catalyst is immobilized in the pores forming the three-dimensional network or in the interlayer structure; wherein the fuel cell comprises the immobilized peroxide decomposition catalyst within the range of 0.01 to 80 mass-% with respect to the mass of the polyelectrolyte; and wherein the particle diameter of the support is from 0.001 μm to 20 μm (both inclusive).
