	Fuel Cells For Electric Power Generation: Peculiarities And Dedicated Solutions For Power Electronic Conditioning Systems   By F. Profumo, A. Tenconi, M. Cerchio, R. Bojoi, G. Gianolio	[View]   [Download]
Abstract: The Fuel Cells (FC) output power is usually generated at low voltage. The output DC voltage is not constant and it depends on the operation conditions. Furthermore, FC have dynamic responses that are slower than the transient responses which are typically requested by the loads; hence, in many applications, the FC generators must be interfaced with other energy/power sources. For these reasons, the FC stack output power and/or the batteries/supercapacitors input/output power, must be usually conditioned by means of an electronic power converter. The main purpose of the paper is to present the issues related to the conditioning of FC power output; in particular, considering the specific requirements of the interface electronic converters in the two most important applications: mini/micro distributed generation (or cogeneration) and the transportation systems. The paper mainly discusses the most important circuit topologies of the DC/DC converters dedicated to the FC power conditioning, in particular considering the Proton Exchange Membrane FC technology.
