Abstract
An apparatus configured for controlling emergency driving for a fuel cell vehicle may include a failure detector configured to detect whether a purge valve and a drain valve fails; a determination portion configured to measure voltages of channels of a fuel cell stack to determine whether stability of the fuel cell stack is secured; and a controller configured to control, when the stability of the fuel cell stack is not secured and a failure occurs on one or more of the purge valve and the drain valve, one or more of an operating pressure and an operating temperature of the fuel cell stack and a current applied to the fuel cell stack.
Claims19
An apparatus of controlling emergency driving for a fuel cell vehicle, the apparatus comprising:
- a failure detector configured to detect when at least one of a purge valve and a drain valve of a hydrogen supply device fails;
- a determination portion configured to measure voltages of channels of a fuel cell stack connected to the hydrogen supply device to determine when stability of the fuel cell stack is secured;
- and
- a controller configured to control at least one of an operating pressure and an operating temperature of the fuel cell stack and a current value applied to the fuel cell stack, upon determining that the stability of the fuel cell stack is not secured and a failure occurs on the at least one of the purge valve and the drain valve.
A method of controlling emergency driving for a fuel cell vehicle, the method comprising:
- detecting, by a failure detector, when at least one of a purge valve and a drain valve of a hydrogen supply device fails;
- measuring, by a determination portion, voltages of channels of a fuel cell stack connected to the hydrogen supply device to determine when stability of the fuel cell stack is secured;
- and
- when the stability of the fuel cell stack is not secured and a failure occurs on the at least one of the purge valve and the drain valve, controlling, by a controller, at least one of an operating pressure and an operating temperature of the fuel cell stack and a current value applied to the fuel cell stack.
