A small-signal equivalent circuit model for PEM fuel cells

Present-day fuel cells have transient responses that are much slower than those of the typical power conditioner that they interact with. Hence, there is significant motivation to have an equivalent circuit model of the PEM fuel cell's small-signal behavior, as is derived in this paper, for analysis and optimal design of the integrated power systems based on such sources and of their control. Comparison of step load test results to the circuit simulations shows good agreement with each other
