Abstract
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. Examples of impurities in the product stream include; carbon monoxide, carbon dioxide, methane and water.
