钢带捆扎燃料电池电堆端板尺寸和形状优化
Size and Shape Optimization of the Steel Banding Fuel Cell Stack End Plate
摘要
Abstract
The end plate of fuel cell stack with a metal bipolar plate is easily deformed under assembly pressure.A novel designed structure of the end plate was presented and its parameters was optimized by the numerical simulation based on the finite element method.A structural mechanics analysis model for the end plate was created by Ansys Apdl program and the Ansys Workbench software,and the size and shape optimization algorithm was introduced.The higher uniformity among steel bands force,less weight of end plate,and lower deviation of the fixed bolt axis are objective functions.The influence of the variable size and shape dimensions on the above objective functions was analyzed,aiming to determine the optimized size and shape of end plate,and improve the contact pressure uniformity between the components and the stress behavior of the steel handing.A 2D quarter stack model which has 11 layers to compare the contact pressure uniformity between bipolar plate and MEA (membrane electrode assembly).关键词
