Asahi Glass Co., Ltd. (AGC) and Honda R&D Co., Ltd. have developed jointly a new electric double layer capacitor (EDLC) as an energy storage device for fuel cell vehicles. This EDLC has been utilized in the Honda FCX fuel cell vehicle marketed in December 2002. High reliability, high input/output power and high energy density are required of the EDLC installed in Honda FCX fuel cell vehicle. The selected materials as electrode, electrolyte and separator realized to these high requirements. In the first, the results of the joint-development about these materials are described. As the second, the performances of recent AGC ultra-capacitor prototypes using the newly developed materials and capacitor modules composed of the prototypes are presented.
