Fuel cell systems and methods for controlling the operation of components of the fuel cell system, which may include a fuel source and a fuel cell stack. In some examples, a fuel source is adapted to provide supply fuel to a fuel cell stack at a supply pressure. The fuel cell stack produces electric current at a production amperage. In some examples, a control system is adapted to control operation of the fuel cell stack based on a pressure detected at the fuel cell stack. In some examples, a target production amperage is determined based on the detected pressure, such that when electric current is produced at the target production amperage for the detected pressure, the fuel cell stack consumes a predetermined proportion of the supply fuel.

L'invention concerne des systèmes de pile à combustible et des procédés de contrôle du fonctionnement des éléments du système de pile, pouvant comprendre une source de combustible et un assemblage de piles. Selon certains exemples, une source de combustible alimente un assemblage à une pression d'alimentation. L'assemblage produit un courant électrique à un ampérage de production. Selon certains exemples, un système de contrôle assure le contrôle de l'assemblage en fonction d'une pression détectée à l'assemblage. Selon certains exemples, un ampérage de production cible est déterminé en fonction de la pression détectée, de sorte que lorsque le courant électrique est produit à l'ampérage de production cible pour la pression détectée, l'assemblage consomme une partie préétablie du combustible de l'alimentation.
