CA 2662381

The invention relates to a method for determining an anode performance of a fuel cell or a fuel cell stack (20). The invention is characterized in that the anode performance is determined by measuring at least one current of the fuel cell or the fuel cell stack (20), an air volume flow supplied to an afterburner (24), no fuel being fed during measuring, an excess-air coefficient of a reformer gas and an oxygen volume content in an afterburner gas.

L'invention concerne un procédé de détermination d'un rendement d'anode dans une pile à combustible ou dans un empilement de cellule électrochimique (20). Selon l'invention, le rendement d'anode est déterminé par la mesure d'au moins un flux de la pile à combustible ou de l'empilement de cellule électrochimique (20), d'un débit volumétrique d'air amené à un brûleur de post-combustion (24), aucun combustible n'étant mis en contact avec cet air au moment de la mesure, d'un coefficient d'air du gaz de reformeur et d'une fraction volumique d'oxygène dans les effluents gazeux du brûleur de post-combustion.
