For the problems of different parameters PEMFC (Proton Exchange Membrane Fuel Cell) applied to dc micro-grid at the same time, the basic framework of two parallel PEMFC dc power supply system was put forward in this paper, meanwhile, the characteristics of this system was analyzed. For the problem of branch current distribution of parallel system, this paper set up the small signal mathematical model of BUCK connected in parallel, designed the control circuit of current-sharing of this system. Finally ,the simulation experiments verified the accuracy and rapidity of current sharing and the reliability and stability of this system, when the sub-circuit was fault.

Abstract This paper describes a Proton Exchange Membrane (PEM) fuel cell system model for automotive applications that includes an air compressor, cooling system, and other auxiliaries. The fuel cell system model has been integrated into a vehicle performance simulator that determines fuel economy and allows consideration of control strategies. Significant fuel cell system efficiency improvements may be possible through control of the air compressor and other auxiliaries. Fuel cell system efficiency results are presented for two limiting air compressor cases: ideal control and no control. Extension of the present analysis to hybrid configurations consisting of a fuel cell system and battery is currently under study.

Current Fed Step-up DC/DC Converter for Fuel Cell Inverter ApplicationsIn order to use hydrogen fuel cells in domestic applications either as main power supply or backup source, their low DC output voltage has to be matched to the level and frequency of the utility grid AC voltage. Such power converter systems usually consist of a DC-DC converter and a DC-AC inverter. Comparison of different current fed step-up DC/DC converters is done in this paper and a double inductor step-up push-pull converter investigated, presenting simulation and experimental results. The converter is elaborated for 1200 W power to match the rated power of the proton exchange membrane (PEM) fuel cell located in hydrogen fuel cell research laboratory of Riga Technical University.
