Abstract
An electric vehicle with fuel cells mounted thereon has a fuel tank that stores a fuel therein, and a connector receptor that is connected to the fuel tank and is open to the surface of the vehicle body. A connector of a predetermined hydrogen supply device is fitted in and attached to the connector receptor, so that a supply of fuel is fed from the hydrogen supply device to the electric vehicle. The connector receptor is provided with a fuel lid for covering over the connector receptor. When it is determined that the fuel cells are in a working state, the fuel lid is not opened in response to input of an opening instruction of the fuel lid in the course of fuel supply. When it is determined that the fuel lid is open, on the other hand, operation of the fuel cells is not started in response to input of a starting instruction of the fuel cells in the electric vehicle. Such an arrangement enhances the safety of fuel supply to any system with fuel cells.
Description
TECHNICAL FIELD [0001]The present invention relates to a fuel supply system for fuel cells and a movable body. Specifically the present invention pertains to a fuel supply system for fuel cells, which functions to supply a fuel for the fuel cells or a source material used to generate the fuel for the fuel cells, as well as to a movable body.BACKGROUND ART [0002]A diversity of electric vehicles have been proposed, which utilize electrical energy output from fuel cells for the driving energy. Supply of a fuel, such as hydrogen, to the fuel cells is naturally required for power generation in the fuel cells. The electric vehicle of one known construction has hydrogen mounted thereon as the fuel for the fuel cells. The electric vehicle of another known construction has a source material, such as a hydrocarbon or a hydrocarbon compound, mounted thereon and reforms the source material to generate hydrogen gas and supply the hydrogen gas to the fuel cells.[0003]One proposed arrangement to m...
