弗劳恩霍夫太阳能系统研究所ISE开发了一种燃料电池系统，为便携式计算机提供动力。这些部件是四电池聚合物电解质膜燃料电池（PEMFC）系统、六相DC/DC转换器、空气泵、两个圆柱形金属氢化物储罐、用于调节氢气流量的阀和压力传感器[国家专利申请，DE 101 19 339，03（2001）]以及用于管理整个系统的控制单元。该系统的突出特征是燃料电池堆和集成的DC/DC转换器的扁平设计[已授权的国家专利DE 198 10 556 C1，11（1999）]。该系统在12 V下提供约42 W的标称功率输出。广泛的物理调查不同的流场组合以及系统设计。
The Fraunhofer Institute for Solar Energy Systems ISE has developed a fuel cell system to power a portable computer. The components are a four-cell polymer electrolyte membrane fuel cell (PEMFC) system, a six-phase DC/DC-converter, an air pump, two cylindrical metal hydride storage tanks, a valve and a pressure sensor to adjust the hydrogen flow [national patent applied, DE 101 19 339, 03 (2001)] and a control unit for the management of the whole system. Prominent characteristics of the system are a flat design of the fuel cell stack and the integrated DC/DC-converter [national patent granted, DE 198 10 556 C1, 11 (1999)]. The system provides a nominal power output of about 42W at 12V. Extensive physical investigations of different flow field combinations as well as the system design are presented.
