Optimization of operating parameters for liquid-cooled PEM fuel cell stacks using Taguchi method

다국어 초록 (Multilingual Abstract)

Operating conditions is one of the key factors required to ensure high performance PEM fuel cell stack;careful balance between performance and parasitic loads has to be taken into account to achieve optimum output. This study evaluates numerically key operating parameters of liquid-cooled PEM fuel cell stack with regard to the stack performance, stack efficiency and viability to enhance efficiency utilizing waste heat for combined heat and power. The results indicate that high stack performance does not always associate with high stack efficiency due to higher parasitic load; it is recommended to optimize the operating parameters in terms of efficiency.
