APPARATUS FOR DISCHARGING LEAKAGE HYDROGEN OF ENGINE ROOM FOR FULL CELL BUS

摘要

PURPOSE: An apparatus for compulsorily discharging leakage hydrogen of an engine room for a fuel cell bus is provided to rapidly discharge the leakage hydrogen of the engine room of the fuel cell bus using a fan and an exhaust pipe. CONSTITUTION: A fan(11) is arranged on a roof panel to exhaust the air of an engine room to the atmosphere. An exhaust pipe(12) is arranged on a roof panel to connect the engine room to the atmosphere. An air tank(14) has the inner pressure higher than the atmospheric pressure. One end of An air spray pipe(15) is connected to the exhaust pipe. The other end of the air spray pipe is connected to the air tank. A relay(16) is arranged between both ends of the air spray pipe. A controller(17) controls the driving of the fan and the relay according to the signal of a hydrogen sensor inside the engine room.
