Abstract
A fuel cell system includes: a fuel cell which generates electricity using hydrogen and oxygen; a hydrogen storage which stores hydrogen supplied to the fuel cell and which has a supply port connectable to a hydrogen supply unit for supplying hydrogen from outside the fuel cell system; a detector which detects a leakage of the hydrogen from the hydrogen storage; and a connection controller which regulates connection of the hydrogen supply unit to the supply port when the leakage of the hydrogen is detected by the detector.
Claims18
A fuel cell system, comprising:
- a fuel cell which generates electricity using hydrogen and oxygen;
- a hydrogen storage which stores hydrogen supplied to said fuel cell and which has a supply port connectable to a hydrogen supply unit for supplying hydrogen from outside the fuel cell system;
- a detector which detects a leakage of the hydrogen from said hydrogen storage;
- and
- a connection controller which controls connection of the hydrogen supply unit to the supply port when the leakage of the hydrogen is detected by said detector.
A fuel cell connected to a hydrogen supply unit including a hydrogen supply source for supplying additional hydrogen, a supply outlet connected to the fuel cell and a supply control means provided between the hydrogen supply source and the supply outlet, the fuel cell system comprising:
- a fuel cell which generates electricity using hydrogen and oxygen;
- a hydrogen storage which stores hydrogen supplied to said fuel cell and which has a supply port connectable to the hydrogen supply unit for supplying hydrogen from outside the fuel cell system;
- a detector which detects a leakage of the hydrogen from said hydrogen storage;
- and
- a structure deformation section provided in a position counter to the hydrogen supply unit,
- wherein when the leakage of the hydrogen is detected, said structure deformation section deforms a structure thereof.
A hydrogen supply unit connectable to a fuel cell system including a fuel cell for generating electricity using hydrogen and oxygen and a hydrogen storage for storing the hydrogen, the hydrogen supply unit comprising:
- a hydrogen supply source which supplies hydrogen to the hydrogen storage;
- a supply outlet connected to the fuel cell system;
- and
- a supply control means provided between said hydrogen supply source and said supply outlet,
- said supply control means including:
- a movable part;
- and
- a supply control valve,
- wherein the supply control means includes:
- a movable part;
- and a supply control valve, and wherein when the hydrogen supply unit is connected to the fuel cell system and the movable part comes in contact with the fuel cell system and is moved thereby, the supply control valve closes so as to control supplying the hydrogen from the hydrogen supply source.
