The invention discloses a hydrogen leakage prevention device for a marine fuel cell system, comprising a protective part, a nitrogen injection mechanism, a pressure detection part, a hydrogen concentration detection part and a vacuuming mechanism; The beneficial effect of the present invention is that: the shield is set on the marine fuel cell system, and nitrogen is injected into the shield through the nitrogen injection mechanism, so that all hydrogen-related parts of the marine fuel cell system can be inerted. , reduce the risk of hydrogen accumulation. At the same time, the pressure detection part continuously detects the gas pressure in the protective cavity, and the hydrogen concentration detection part continuously detects the hydrogen concentration in the protective cavity, so that the marine fuel cell can be detected through the pressure detection part and the hydrogen concentration detection part. Whether hydrogen leakage occurs in the system, when hydrogen leakage is detected, the gas in the protective chamber is extracted and discharged into the atmosphere through the vacuum pumping mechanism to prevent accidents caused by hydrogen accumulation. |
