Patent

CA 2420887

A method and apparatus for protecting the anode of a solid oxide or molten carbonate fuel cell from oxidation includes a controller having a voltmeter for monitoring the voltage output of the fuel cell and an external electric power source. If the fuel cell voltage output drops below a predetermined level, the controller causes the power source to be applied to the fuel cell which results in oxygen being transported away from the anode.

L'invention concerne un procédé et un appareil pour protéger, contre l'oxydation, l'anode d'une pile à combustible à oxyde solide ou à carbonates fondus, qui consistent en un régulateur doté d'un voltmètre pour surveiller la sortie de tension de la pile à combustible et d'une source électrique externe. Si la sortie de tension de ladite pile descend en dessous d'un niveau prédéterminé, le régulateur fait appliquer la source électrique à la pile à combustible, ce qui a pour résultat d'éloigner l'oxygène de l'anode.
