The aim of this paper is to improve the reliability of Proton Electrolyte Membrane Fuel Cell (PEMFC) stack by designing the clamping force and the thickness difference between the membrane electrode assembly (MEA) and the gasket. The stack reliability is directly determined by the component reliability, which is affected by the material property and contact stress. The component contact stress is...
A simplified analysis method for large proton exchange membrane fuel cell (PEMFC) stack is proposed to obtain the optimal clamping force if the stack is subjected to an impact acceleration. The PEMFC stack is first simplified to an equivalent stiffness-mass model consisting of a number of springs and point masses in order to get the parameterized structural characteristics. Based on this model, the...
