Production Method Feasibility for High Power Density Fuel Cell Bipolar Plates

PEM燃料电池的双极板通常占燃料电池堆重量和体积的一半以上，成本在15-30%之间。ITM Power已经开发出高功率密度燃料电池mea，目前正在进行商业应用的研究。为了充分发挥高功率密度mea的优势，减少燃料电池的尺寸和重量，这些mea需要在低成本和低重量/体积的堆叠架构中使用。该项目将研究用低成本/小体积金属板材生产双极板的液压成形工艺的可行性。

Bipolar Plates for PEM Fuel Cells Typically account for more than half of the fuel cell stacks weight and volume, and between 15-30% of its costs. ITM Power have developed high power density fuel cell MEAs which are currently undergong investigations for commerical applications. In order to fully realise the benefits of high power density MEAs ability to reduce fuel cell size and weight these MEAs need to be used in stack arcitechture whcih is also low cost and low weight/volume. This project will investigate the feasibility of the hydroforming process to produce bipolar plates from low cost/low volume metal sheets.
