Technical Field
The invention belongs to the technical field of deep sea power supplies, and particularly relates to a deep sea hydrogen fuel cell system.
Background
The power supply is the core power of deep sea equipment and is an important guarantee for realizing deep sea scientific investigation, detection operation and deep sea resource development. In deep sea environment, the traditional primary batteries (zinc-manganese batteries, zinc-silver batteries and the like) and secondary batteries (lead-acid batteries, lithium ion batteries and the like) are difficult to meet the requirements of deep sea equipment on high-power, long-service-life, safe and reliable power supplies. The hydrogen fuel cell is a green energy device with high power density, low-temperature operation, no noise and no pollution, and can be used as an ideal power source of deep sea equipment. The traditional hydrogen fuel cell takes hydrogen as fuel, and the hydrogen source is mainly provided by high-pressure gaseous hydrogen storage or low-temperature liquid hydrogen storage equipment which is carried. However, the deep sea environment not only brings higher cost to the storage, transportation and application of hydrogen, but also brings more serious potential safety hazard problems, and further restricts the deep sea application of the hydrogen fuel cell. Both of the patent applications No. 200810228230.8 and No. 201210562567.9 propose combining a hydrogen-oxygen fuel cell with a metal air or oxygen cell and utilizing hydrogen gas generated by corrosion of the cell anode as a source of hydrogen. On the one hand, however, the corrosion hydrogen evolution of the anode of the metal air or oxygen battery is a side reaction, and the hydrogen yield is low and unstable, so that the hydrogen is difficult to be effectively utilized; on the other hand, in the deep sea oxygen-free environment, the metal air or oxygen battery is difficult to work, and cannot be used as a stable hydrogen source of the fuel cell. Therefore, the hydrogen source problem of the hydrogen fuel cell in the deep sea environment is solved, and the development of the hydrogen fuel cell system for the deep sea has important practical application value.
