    • 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 .
    • 一种燃料电池系统,包括控制器,温度传感器,其具有物理存在于所述系统内的管道中,以测量所述导管内的点处的流体的温度(T g)和用于感测所述管道内温度的壁温度传感器 导管壁(T w)。 控制器将T g和T w作为输入,并应用已知常数的方程式计算T g基于局部流动温度和几何尺寸的测量误差,并达到计算温度。 可以迭代地应用该方程,直到计算的温度和T g之间的差值低于可接受的值时,然后可以将所计算的温度假设为在T g测量点处的实际气体温度的精确表示。 计算方向由T g和T w之间的相对差值控制。
