The present invention provides a fuel cell comprising: a cathode catalyst layer 2; an anode catalyst layer 3; a membrane electrode assembly 1 including a proton conductive membrane 6 disposed between the cathode catalyst layer 2 and the anode catalyst layer 3; a cathode conductive layer 7a provided to a side of the cathode catalyst layer of the membrane electrode assembly 1; an outer case 15 having an air intake port 14 for supplying an air to the cathode catalyst layer 2; an anode conductive layer 7b provided to a side of the anode catalyst layer of the membrane electrode assembly 1; and a liquid fuel tank 9 for storing a fuel and supplying the fuel to the anode catalyst layer 3; wherein the cathode conductive layer 7a and the anode conductive layer 7b are integrated onto one sheet of insulating film 16 and the integrated insulation film 16 is folded in two so that the membrane electrode assembly 1 is accommodated in an inner space formed in the folded insulating film 16.
La pile à combustible objet de l~invention comprend : un corps de raccordement film-électrode (1) disposant d~un film conducteur de protons (6) entre une couche catalytique de cathode (2) et une couche catalytique d~anode (3) ; une couche conductrice de cathode (7a) placée sur le côté de la couche catalytique de cathode du corps de raccordement film-électrode (1) ; une enveloppe extérieure (15) dotée d~une ouverture d~entrée d~air (14) pour alimenter en air la couche catalytique de cathode (2) ; une couche conductrice d~anode (7b) placée sur le côté de la couche catalytique d~anode du corps de raccordement film-électrode (1) et un réservoir de combustible liquide (9) contenant le combustible liquide pour alimenter la coche catalytique d~anode (3). La couche conductrice de cathode (7a) et la couche conductrice d~anode (7b) sont placées sur un film isolant (16) afin de former un ensemble unique à deux plis. Le corps de raccordement film-électrode (1) est contenu par un espace intérieur formé par les deux plis.
