An electrochemical fuel cell having a membrane electrode assembly (1) and a flow field (4) adjacent thereto wherein the flow field comprises an electrically conductive porous material having a porosity of at least 50 percent and a mean pore size of at least 35 microns. This fuel cell is able to operate at relatively high current densities and relatively high voltages at reduced gas flow rates.
Pile à combustible électrochimique possédant un ensemble (1) électrode à membrane et un champ d'écoulement (4) contigu audit ensemble et composé d'un matériau poreux électriquement conducteur dont la porosité est d'au moins 50 % et la dimension moyenne de pore d'au moins 35 microns. Cette pile à combustible est capable de fonctionner à des densités de courant et à des tensions relativement élevées à des débits de gaz limités.
