Problems solved by technology

[0003] As the power source of fuel cell vehicles, due to its complex structure, harsh working environment and frequent changes in operating conditions, various faults will inevitably occur in the vehicle fuel cell system. Treatment measures, ranging from causing the system to fail to work normally or efficiently, to causing irreversible permanent damage to the stack or major safety accidents such as hydrogen and electricity
However, the maintenance and repair of existing fuel cell vehicles generally adopts the maintenance and repair methods of traditional fuel vehicles, which cannot timely and effectively detect and sample the corresponding treatment measures for the fuel cell system components used in vehicles, and there are great potential safety hazards
[0004] Therefore, for the problem that fuel cell vehicles in the related art cannot timely and effectively detect the vehicle fuel cell system components and take corresponding measures, no effective solution has been proposed yet.
