Control strategy of cooling system for the optimization of parasitic power of automotive fuel cell system

摘要

Thermal management (TM) is one of the key factors required to ensure good performance of fuel cell stacks. In this study, thermal management strategies for a fuel cell system are presented to evaluate the parasitic power of the cooling system with changes of operating temperature of a PEMFC system. The fuel cell system model is composed of a dynamic fuel cell stack model to express heat generation and a detailed dynamic cooling module. The stack model uses an analytic approach; the cooling system model is composed of a radiator, fan, reservoir, water pump and three way valve.
