The fuel cell module can thus be permanently held at the optimal operating point thereof. The fuel cell module preferably comprises HT-PEM fuel cells, which in contrast to PEM fuel cells work at a higher temperature, in particular in the range 120 C.° to 200 C.°.Type: ApplicationFiled: April 30, 2003Publication date: January 29, 2004Inventors: Rolf Bruck, Joachim Grosse, Manfred Poppinger, Meike Reizig

Publication number: 20040017183Abstract: A power glitch free internal voltage generation circuit includes: a voltage divider for dividing level of an internal voltage; a reference voltage generator generating a reference voltage having a predetermined voltage level by dividing a level of an external voltage; a comparator connected to the external voltage and the internal voltage and comparing the divided internal voltage with the reference voltage to generate a compared output; and a driver for supplying the external voltage to the internal voltage in response to the output of the comparator. In this manner, a high voltage level from either of the external voltage and the internal voltage is used as a source of the comparator. This, in turn, stably maintains the internal voltage because the driver for transferring the external voltage to the internal voltage is intercepted in the case where a glitch occurs that lowers the external voltage to a level lower than the internal voltage.Type: ApplicationFiled: July 16, 2003Publication date: January 29, 2004Applicant: Samsung Electronics Co., Ltd.Inventor: Sung-Hee Cho
