Problems solved by technology

Vehicle-mounted fuel cell system integration generally adopts decentralized layout and integrated frame layout according to the overall layout requirements. The existing layout of vehicle-mounted fuel cell systems has problems such as low insulation value, poor dustproof and waterproof effects, or difficult maintenance.
[0003] In order to solve the above-mentioned shortcomings, the existing vehicle-mounted fuel cell system adopts an insulating material to wrap and isolate the stack, but there are still insulation faults during operation, and insulation monitoring is required before operation. On the one hand, there is a reduction in the net output power of the fuel cell system. On the other hand, there is also the risk of high voltage electric shock
