PEFC System Reactant Gas Supply Management and Anode Purging Strategy: An Experimental Approach

In this report, a 5 kW PEFC system running on dry hydrogen with an appropriately sized Balance of Plant (BoP) was used to conduct experimental studies and analyses gas supply subsystems. The improper rating use BoP components has been found increase parasitic loads, which consequently direct effect the polymer electrolyte fuel cell (PEFC) efficiency. Therefore, minimisation loads while maintaining desired performance is crucial. Nevertheless, little in literature regarding work large stacks BoP, majority papers concentrating modelling. A particular interest our study anode side cell. Additionally rationale behind recirculation scrutinised, novel purging strategy developed implemented. Through modelling, cathode air blower minimised since it be biggest contributor loads.
