Description
Summary:Deployment of polymer electrolyte fuel cell vehicles commercially requires the development of a robust hydrogen fueling infrastructure. This is coupled with the need for high purity hydrogen fuel necessary to maintain fuel cell engine performance and durability over the life of the vehicle. In this paper, we discuss the development of an electrochemical hydrogen contaminant detector (HCD) to sense the presence of impurities in hydrogen fuel. Specifically, the role that mass transport plays on the HCD response is discussed. Electrolyte development is highlighted, in with focus on the effects of thickness on detecting the presence of contaminants. Further work on humidity independent electrolytes is provided, along with a brief discussion on the response measured during high pressure testing.
