Abstract
Electrolyte membrane electrode structures that constitute a fuel cell according to the present invention have a staggered arrangement wherein a part of an anode electrode faces a part of one of two adjacent cathode electrodes, with an electrolyte membrane being interposed therebetween, and another part of the anode electrode faces a part of the other cathode electrode, with an interconnect part being interposed therebetween, said interconnect part being formed in the electrolyte membrane. The electrolyte membrane electrode structures are sealed in a laminate layer which is obtained by bonding an anode-side porous film that covers the anode electrode and a cathode-side porous film that covers the cathode electrodes with each other.
