20100062315 | METHANOL FUEL CELL CARTRIDGE - The present invention provides a cartridge for a methanol fuel cell at low cost, which does not show deterioration in electric power generation performance, can be operated for a prolonged period of time, and can be reduced in size and weight. In the present invention, the cartridge for a methanol fuel cell has an inner resin layer containing a resin having such a property that, after a film of the resin is immersed in methanol at 60° C. for 7 days, the methanol is diluted twice in terms of a volume ratio with distilled water at room temperature to give a liquid, the liquid shows a light transmittance of 10% or higher at 300 nm. | 03-11-2010 |
20100104907 | ELECTRONIC DEVICE - In an electronic device, state detection elements are arranged at various locations of a fuel cell system supplies an electric power to a phone unit, the state detection elements detect states of the fuel cell system at the locations. A cell state detection unit detects an operating state of the fuel cell from an output signal of each of the state detection elements. A determination unit determines an operating mode to prompt action to be taken for the operating state of the fuel cell detected by the cell state detection unit. A content of the operating mode is displayed with an image of a character or a fictitious creature based on a determination by the determination unit. | 04-29-2010 |
