Abstract
Description
Technical Field
[0001] This invention relates to the field of fuel cell system application technology, specifically to off-grid hydrogen fuel cell backup power equipment for data centers based on wind, solar and green hydrogen refueling. Background Technology
[0002] With the rapid development of hydrogen fuel cell technology, proton exchange membrane fuel cells, as a new energy device, offer advantages such as rapid start-up at room temperature, high efficiency, low noise, and zero pollution. Given that traditional communication base station power supplies use gasoline / diesel generators, which are environmentally unfriendly and have increased carbon emissions and costs, hydrogen fuel cells can compensate for these shortcomings by replacing them as the main power source. The current base station power supply system mainly consists of mains power and mobile power. When the mains power input is normal, it supplies power to the loads within the base station. When the mains power is interrupted, electrochemical batteries such as lead-acid batteries or lithium-ion batteries supply power to the base station's communication loads.
[0003] The main components of an off-grid hydrogen fuel cell for wind, solar, and green hydrogen replenishment include wind and solar power modules, a water electrolysis hydrogen production system, a hydrogen storage device, a hydrogen fuel cell stack, and an intelligent control system. During operation, the wind and solar power modules are first activated via the intelligent system. When sunlight and wind energy are sufficient, some of the electricity is directly supplied to the load, and excess electricity is sent to the water electrolysis hydrogen production system to produce hydrogen, which is then stored in the hydrogen storage device. When wind and solar power generation is insufficient or nonexistent, the system instructs the hydrogen storage device to supply hydrogen to the fuel cell stack, which then starts generating electricity to supply the load. During operation, the intelligent system monitors the power generation, hydrogen storage, and fuel cell stack power in real time, dynamically adjusting each component to ensure a stable power supply. Before shutdown, hydrogen production is stopped first. After the hydrogen storage device stops supplying hydrogen and the fuel cell stack has no output, all modules are shut down, and equipment inspection and maintenance are performed.
[0004] In a wind-solar-green hydrogen energy replenishment system, the output characteristics of photovoltaic and wind power are directly constrained by natural conditions, exhibiting significant intermittency and fluctuation. During the day, the intensity of sunlight changes drastically with cloud cover and sunrise and sunset. For example, photovoltaic power can reach its rated value during strong midday sunlight, but may drop to less than 10% of the rated value on cloudy days or in the evening. Wind power is more affected by wind speed and direction. Instantaneous gusts may double the power in a short period of time, while during windless periods, it may fall into a long period of zero output. When this unstable electrical energy is directly input into the electrolyzer, it will cause frequent fluctuations in the supply voltage and current of the electrolyzer. Summary of the Invention
