Abstract
The level of electrical current produced by a fuel cell during rapid changes in the power demanded by a load, is clamped to the fuel cell's maximum rated current value in order to avoid damage to the fuel cell. When the current supplied to the load by the fuel cell overshoots the maximum rated current value, the fuel cell current is immediately reduced by increasing the fuel cell voltage.
