一种新的方法，质子交换膜燃料电池堆的制造已被证明。该方法基于使用轻质金属导电元件以及由工程热塑性塑料制造的非导电元件，以产生可以使用廉价的大规模生产技术由原材料的平板制造的轻质堆叠。这里描述的堆具有超过520 W的功率输出，来自616 mt的体积和539 g的质量，功率密度为967 W/kg和846 W/L，同时在103 kPa的压力下以53%的转换效率操作。预计通过进一步改进，可以生产功率密度超过1，500 W/kg和1，200 W/L的PEM燃料电池堆。(C)1998爱思唯尔科技有限公司版权所有。
A new approach to PEM fuel cell stack fabrication has been demonstrated. This approach is based on the use of light weight metal conductive elements together with nonconductive elements fabricated from engineering thermoplastics to yield a lightweight stack that can be manufactured from flat sheets of stock materials using inexpensive mass production techniques. The stack described here has a power output of over 520 W from a volume of 616 mt and a mass of 539 g for a power density of 967 W/kg and 846 W/L while operating at a pressure of 103 kPa with a 53% conversion efficiency. It is projected that with further refinement, PEM fuel cell stacks with power densities over 1,500 W/kg and 1,200 W/L can be produced. (C) 1998 Elsevier Science Ltd. All rights reserved.
