Development of an equivalent circuit model of a fuel cell to evaluate the effects of inverter ripple current Conference Paper

abstract

• In this paper an impedance model of the Proton Exchange Membrane Fuel Cell Stack (PEMFCS) is proposed. The proposed study employs an equivalent circuit of the PEMFCS derived by frequency response analysis (FRA) technique. An equivalent circuit for the fuel cell stack is developed to evaluate the effects of ripple currents generated by the power-conditioning unit. The calculated results are then verified by means of experiments on three commercially available fuel cells: Avista Labs SR-12 (500W), Ballard Nexa (1.2kW) and BCS-Tech (300W) PEMFC system. The relationship between ripple current and fuel cell performance: such as power loss and fuel consumption is investigated. Experimental results show that the ripple current can contribute up to 10% reduction in the available output power.
