Abstract
The invention provides a fuel cell system suitable for an underground coal mine, the fuel cell system comprises a hydrogen source, an oxygen source and a galvanic pile, the galvanic pile is provided with an anode inlet, an anode outlet, a cathode inlet and a cathode outlet, the hydrogen source is communicated with the anode inlet of the galvanic pile, the oxygen source is communicated with the cathode inlet of the galvanic pile, the cathode outlet of the galvanic pile is closed through a cathode exhaust regulating valve, an anode exhaust dehydrogenation device is mounted on a pipeline communicated with the anode outlet of the electric pile and is used for eliminating hydrogen in an anode exhaust pipeline. According to the fuel cell system disclosed by the invention, the anode exhaust dehydrogenation device is mounted on the pipeline communicated with the anode outlet of the electric pile, so that hydrogen which is not completely reacted in the anode exhaust pipeline can be eliminated, the hydrogen is prevented from being discharged out of a mine to form local accumulation, and the underground safety of the mine is improved.
Description
technical field [0001] The invention relates to the technical field of fuel cells, in particular to a fuel cell system suitable for underground coal mines. Background technique [0002] Confined space refers to the interior of various equipment in the factory (furnace, tower kettle, tank, warehouse, pool, tank car, pipe, flue, etc.) and the tunnel, sewer, ditch, pit, well, pool of the city (including the factory) , culverts, valve rooms, sewage treatment facilities and other closed and semi-closed facilities and places (cabins, underground concealed projects, airtight containers, facilities that have not been used for a long time or places with poor ventilation, etc.), as well as rural storage of sweet potatoes, potatoes, various Vegetable wells, cellars, etc. Poorly ventilated mines should also be considered confined spaces, which are also explosive atmospheres. [0003] During the underground mining of coal mines, dust particles and toxic and harmful gases (CO, SO 2 , N...
