Problems solved by technology

[0007] The above solutions either have the risk of causing the stack to fail, or the design of the circuit is complex, and the fuel cell system will be cut off when the insulation value is lower than the insulation alarm value. The fuel cell system cannot continue to be used until the insulation fault is resolved.

Abstract

The invention discloses a vehicle-mounted fuel cell system. The vehicle-mounted fuel cell system comprises a fuel cell box body, a first liquid passing pipe for guiding cooling liquid, a first inner connecting pipe connected with the first liquid passing pipe and located in the fuel cell box body, and a first outer connecting pipe connected with the first liquid passing pipe and located outside the fuel cell box body, a first connecting flange is arranged on the first liquid passing pipe, the first connecting flange is connected with the fuel cell box body, and gaps are formed between the first inner connecting pipe and the first connecting flange and between the first outer connecting pipe and the first connecting flange. According to the vehicle-mounted fuel cell system, the fuel cell cooling liquid inlet, the fuel cell cooling liquid outlet and the cooling loop are subjected to insulation design, it is ensured that the whole fuel cell vehicle system still has the good insulation performance even in a humid and hot environment, and the running safety of the whole vehicle can be improved. The invention also discloses a fuel cell vehicle.

Description

technical field [0001] The invention belongs to the technical field of new energy vehicles, in particular, the invention relates to a vehicle-mounted fuel cell system and a fuel cell vehicle. Background technique [0002] A fuel cell is a power generation device that directly converts chemical energy into electrical energy through an electrochemical reaction. It has the advantages of high efficiency, high power, long life, high reliability, low noise, and no harmful emissions. Due to its long cruising range and short hydrogenation time, fuel cell vehicles have become an important development direction of new energy vehicles, and have great application potential in the field of transportation. [0003] Vehicle-mounted fuel cell system integration generally adopts decentralized layout and integrated frame layout according to the overall layout requirements, and uses silicone pipes or stainless steel pipes to connect the stack with electronic water pumps, temperature control va...
