ABSTRACT:
A sensor for monitoring the lambda of a component of a reactant feed stream flowing through a fuel cell stack. The sensor comprises one or more fuel cells that are sensitive to a change in lambda of a specific component of a reactant feed stream flowing through the fuel cell. The sensitivity of the fuel cell causes a voltage produced by the lambda sensing fuel cell to vary in response to variation in the lambda of the specific component. The variation of the voltage output can be modeled and/or compared to empirical data to correlate the voltage output to the lambda of the specific component. Based on the lambda of the specific component, the operation of the fuel cell stack can be optimized.
