20200058948 | HUMIDIFIER FOR FUEL CELL - A humidifier for a fuel cell includes: a bundle of hollow fiber membranes disposed therein, such that an intake gas flows inside the bundle of hollow fiber membranes; a housing configured to accommodate the bundle of hollow fiber membranes, such that an exhaust gas, which has a higher humidity than the intake gas, flows inside the housing; and a guide member disposed in the housing to restrict a movement of the bundle of hollow fiber membranes inside the housing. Coolant flows through the guide member to cool the exhaust gas to promote condensation of the exhaust gas. | 2020-02-20 |
20200058949 | APPARATUS AND METHOD FOR CONTROLLING HYDROGEN PURGING - An apparatus and method for controlling hydrogen purging are provided. The hydrogen purging control apparatus includes a purge valve that is disposed at an outlet on an anode side of a fuel cell stack and is configured to adjust an amount of emission of hydrogen containing impurities. Additionally, a controller is configured to adjust an opening and closing cycle of the purge valve based on a required output or an output current of the fuel cell stack. | 2020-02-20 |
20200058950 | BATTERY DEVICE - A battery device having a relatively simple configuration and capable of obtaining a battery output, including a battery container storing a battery solution including an electrolytic solution and a heavy water, an electrolytic anode and cathode that electrolyze a battery solution, an acceleration anode and cathode that accelerate positively charged ions in a battery solution, a collecting anode and cathode that collect charges, an electrolytic power source device that applies electrolytic voltage, and an acceleration power source device that applies acceleration voltage. After applying an electrolytic voltage, when the acceleration power source device applies an acceleration voltage, positively charged ions flow from the acceleration anode to the acceleration cathode, and a collector charge flows from the collecting anode to the collecting cathode through a collector connection line for canceling out the positively charged ions gathered at the acceleration cathode. Part of the collector charge is extracted as a battery output. | 2020-02-20 |
