Patent number: 8404399Abstract: The present invention relates to a fuel cell including: a membrane electrode assembly (2) having a fuel electrode (13), an air electrode (16), and an electrolyte membrane (17) sandwiched therebetween; and a fuel storage unit (4) storing a liquid fuel. The fuel cell is capable of continuously generating electricity for long hours only by being replenished with a fuel, and therefore, attempts have been made to miniaturize the fuel cell to use it as a power source of portable electronic devices. When the membrane electrode assembly and the fuel storage unit in the fuel cell are connected via a flow path, a fuel supply state becomes uneven depending on the shape and the like of the flow path even though a supply amount of the fuel can be adjusted, which causes a problem such as a decrease in an output of the fuel cell.Type: GrantFiled: December 21, 2007Date of Patent: March 26, 2013Assignee: Kabushiki Kaisha ToshibaInventors: Hiroyuki Hasebe, Yukinori Akamoto, Hideyuki Oozu, Hidenori Suzuki, Koichi Kawamura, Yuuichi Sato, Genta Oomichi, Nobuyasu Negishi, Takashi Shimoyamada, Yuichi Yoshida, Hirofumi Kan, Kenichi Takahashi
