Abstract
In an operating liquid feed fuel cell system, fuel concentration in the fuel stream can be calculated as a function of the observed current, the temperature of the fuel stream entering the fuel cell stack, and the temperature of the fuel cell stack itself, thereby eliminating the need for a separate sensor. Typically, methanol will be used as the fuel and the liquid feed fuel cell system will thus be a direct methanol fuel cell system.
