A dynamic model for hydrogen consumption of fuel cell stacks considering the effects of hydrogen purge operation

The actual hydrogen consumption of a fuel cell stack varies with a fixed time delay under the step load change. For each individual stack, the delay time in the step-up load stage is generally shorter than in the step-down stage. Due to the hydrogen purge operation, transient overshoots take place i...
