A fuel cell system comprising a controller, a temperature sensor that has a physical presence in a conduit within the system to measure the temperature of the fluid at a point within the conduit ( T g ) and a wall temperature sensor for sensing a temperature of a wall of the conduit ( T w ). The controller takes T g and T w as inputs and applies an equation with known constants to calculate measurement error of T g based on the local flow temperature and geometry and arrives at a calculated temperature. The equation may be applied iteratively until the difference between the calculated temperature and T g is below an acceptable value when the calculated temperature can then be assumed to be an accurate representation of the actual gas temperature at the T g measurement point. The direction of calculation is controlled by the relative difference between T g and T w . |
