Abstract: A sensor protection device is configured to protect an environmental sensor of a vehicle. The sensor protection device includes a protector that is disposed to face the environmental sensor and configured to be movable with respect to the environmental sensor and includes a movement mechanism configured to provide power to the protector. The movement mechanism has a structure to move the protector.

Abstract: Disclosed is a cleaning solution supply device, and more particularly, a cleaning solution supply device for a fuel cell vehicle. The cleaning solution supply device includes a housing, a mixing pump mounted on the housing and configured to receive water generated during power generation by a fuel cell stack and to mix the received water with a cleaning agent stored in the housing, and a supply line configured to discharge a cleaning solution obtained by mixing the received water with the cleaning agent to an outside of the housing.

Abstract: A fuel cell electric vehicle includes a muffler deicing agent injection system composed of a deicing agent injector injecting a deicing agent, which is pumped by a deicing agent injection pump, from a deicing agent tank and is supplied to a deicing agent pipe. The muffler deicing agent injection system performs a muffler deicing agent injection logic to inject the deicing agent through operations of the deicing agent injection pump and the deicing agent injector by a controller under an ambient temperature satisfaction condition and a deicing agent injection satisfaction condition.
