A review of bop configurations for PEFCs. Experimental study of a suitable topology

This paper presents first a comprehensive review about Balance of Plant (BoP) configurations applied to polymer electrolyte stacks. Taking into account this review, a suitable topology (from our point of view the best) is chosen and analyzed experimentally following a standardized procedure, not only how the stack voltage responds to load current changes (upward and downward) but also to hydrogen pressure, hydrogen flow, stack temperature, stoichiometric rate, fan performance and stack power.
