Problems solved by technology
The cathode side of a hydrogen fuel cell is generally ventilated with air, but compared with land, the sea environment is complex, the air is humid and contains salt spray and more other impurities, the incoming air needs to be filtered, and the general working cycle of unmanned ships Longer, the filter element needs to be replaced after a period of operation, otherwise the filtration efficiency will deteriorate and cause irreversible damage to the hydrogen-air fuel cell
Different from unmanned equipment on land, unmanned equipment at sea has no supply stations or very few stations, and replacing filter elements will bring great inconvenience and additional costs
