PURPOSE:To reduce the power loss due to the resistance of a current cable by cooling the current cable between a cell and an inverter with the liquefied natural gas and keeping it in a high-temperature superconductive state. CONSTITUTION:A high-temperature superconductor which can be cooled with the fuel gas (LNG, liquefied hydrogen) used for a fuel cell, liquefied carbon oxide, or liquefied nitrogen used as the purge gas in a cell storage container is used for a current cable between a fuel cell main body and an inverter. The current cable made of high-temperature superconductive material between the fuel cell main body and the inverter is used for the cell and cooled with liquefied natural gas, liquefied hydrogen, liquefied carbon oxide, or liquefied nitrogen and kept in a superconductive state. A large current (about 2000A for a 1MW-class cell) can be thereby fed easily between the cell and the inverter, and the power loss due to the resistance can be reduced. |
