System and method for early detection of contaminants in a fuel processing system

   
   

A system and method for preventing damage to a fuel cell stack resulting from impurities in the product stream from a fuel processor, such as may occur should the separation region of the fuel processor fail. The system and method include detecting the concentration of at least one component of the product stream and isolating the fuel cell stack should this concentration exceed an acceptable threshold level.

Un sistema y un método para prevenir daño a una célula de combustible apilan resultar de impurezas en la corriente del producto de un procesador del combustible, tal como pueden ocurrir si la región de la separación del fall del procesador del combustible. El sistema y el método incluyen la detección de la concentración por lo menos de un componente de la corriente del producto y aislar el apilado de la célula de combustible si esta concentración excede un límite de alarma aceptable.
