Patent number: 7875999Abstract: A PDA, which functions as an electronic unit, includes power supply which includes a fuel cell unit and an auxiliary power supply which is charged by an output of the fuel cell unit. A non-use state of the PDA is detected by non-use detection unit. Upon detection of the non-use state by the non-use detection unit, the output from the fuel cell unit is stopped and an output of the auxiliary power supply is shut off.Type: GrantFiled: September 23, 2008Date of Patent: January 25, 2011Assignee: Kabushiki Kaisha ToshibaInventors: Hidenori Suzuki, Kiyoshi Senoue, Makoto Miyahara, Kenichi Takahashi, Michiyuki Kitamoto, Yukinori Akamoto, Yoshie Ozeki, Takashi Shimoyamada, Hideaki Yasui, Hiroyuki Hasebe, Koichi Kawamura

Publication number: 20100173212Abstract: In a fuel cell system, a load control unit causes transistor elements to be operated at a timing of every predetermined elapsed periods, so that specific currents having ? and 2? amperes are output. In a degradation detection unit, output voltages Va, Vb are obtained from the ? and 2? amperes, an inclination R(=dv/dI) corresponding to output a resistance Rdmfc is acquired from a difference dv between the output voltages Va, Vb, and an open circuit voltage OCV is obtained from a voltage (Va+dv) obtained by adding the difference dv to the voltage Va. In a judgment unit, the inclination R(=dv/dI) and the voltage OCV are compared with threshold values, respectively, so that the a detection signal indication a degradation of a fuel cell power generation unit is output. Thus, it is possible to detect the cell degradation and to drive a load constantly and stably.Type: ApplicationFiled: March 18, 2010Publication date: July 8, 2010Inventors: Kiyoshi SENOUE, Hidenori Suzuki

Publication number: 20090047556Abstract: The electromotive force of each of power generating cells of a fuel cell unit is compared with a first threshold voltage E1 for the electromotive force of the power generating cells immediately after fuel injection or a second threshold voltage E2 for the electromotive force when the fuel is running out. Using the results of comparison, a decision is made as to whether or not the electromotive forces of all the power generating cells exceed the first threshold voltage E1 within a give time ?1 or whether or not the electromotive force of some of the power generating cells falls below the second threshold voltage E2. An annunciator indicates the results of decision.Type: ApplicationFiled: October 12, 2006Publication date: February 19, 2009Inventors: Hidenori Suzuki, Kiyoshi Senoue
