Abstract
A curve fitting method to approximate power vs. current characteristic curves of a fuel cell as a quadratic is presented. The coefficients of the approximated characteristic curve depend heavily on pressure. The dependence on pressure allows the characteristic curve of a system to be parametrized by fuel cell current and pressure. The curve fitting method presented can be used in a maximum power point tracking algorithm to maximize fuel cell power output. Experimental results are presented to confirm the validity of the method.
