...N. Fekrazad; T. L. Bergman A three-dimensional model is used to predict the power output and internal temperature distribution of a small proton exchange membrane fuel cell stack. Of particular interest is the influence of nonuniform stack compression on thermal conditions inside the fuel cell...

...N. Fekrazad; T. L. Bergman This technical brief reports new findings regarding the strong relationship between the temperature of the bipolar plates of a proton exchange membrane fuel cell stack and thermal conditions within the membranes of the stack. The unique feature of the study is the notion...

...N. Fekrazad; T. L. Bergman A two-dimensional model of a proton exchange membrane fuel cell stack is developed. Taking advantage of the geometrical periodicity of the stack, the model is used to predict the detailed thermal and electrochemical characteristics of the fuel cell. Using recently...

...S. M. Senn; D. Poulikakos In this paper, a thorough model for the porous diffusion layer of a polymer electrolyte fuel cell (PEFC) is presented that accounts for multicomponent species diffusion, transport and formation of liquid water, heat transfer, and electronic current transfer. The governing...
