Problems solved by technology
[0002] At present, the backup power supply is mostly designed on the basis of lead-acid battery, which is characterized by simple design, operation and maintenance of the system and low cost. However, the power density of lead-acid battery is small. Considering the limitations, the overall capacity design is small, which results in the backup power supply only being able to operate for some emergency equipment and the main equipment such as the computer in the control room, and the running time is often short, and it takes several hours to charge for later replenishment capacity

Embodiment Construction
[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0034] A modular fuel cell backup power supply comprising:
[0035] Power generation cabinet, using fuel cells to generate power;
[0036] The control cabinet controls the power generation cabinet to work, and integrates and outputs the electric energy output by the power generation cabinet to the power distribution cabinet;
[0037] Power distribution cabinet, which inverts the DC power input by the control cabinet into AC power, and assists in balancing the load;
[0038] The power generation cabinet includes 8 independent power generation sub-modules. The independence mentioned specifically refers to the layered architecture, rather than parallel connection. Due to the large number of power generation electronic modules, direct parallel connection will inevitably have problems such as DC / DC current sharing at the back end of the ...

The invention discloses a modular fuel cell standby power supply and belongs to the technical field of a fuel cell. The modular fuel cell standby power supply comprises a power generation cabinet forgenerating power by using a fuel cell, a control cabinet which controls the power generation cabinet to work and integrates and outputs electric energy outputted by the power generation cabinet to a power distribution cabinet, the power distribution cabinet which inverts the direct current inputted by the control cabinet into the alternating current and assists in balancing loads, wherein the power generation cabinet comprises a plurality of independent power generation sub-modules. The modular fuel cell standby power supply is advantaged in that the modular fuel cell standby power supply canmeet operation of large-load equipment, is stable and durable in operation, and facilitates later capacity supplement.
Description
technical field [0001] The invention relates to the technical field of fuel cells, in particular to a modular fuel cell backup power supply. Background technique [0002] At present, the backup power supply is mostly designed on the basis of lead-acid battery, which is characterized by simple design, operation and maintenance of the system and low cost. However, the power density of lead-acid battery is small. Considering the limitations, the overall capacity design is small, which results in the backup power supply only being able to run some emergency equipment and the main equipment such as the control room computer, and the running time is often short, and it takes several hours to charge for later replenishment. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned problems in the prior art, and provide a modular fuel cell backup power supply, which can meet the operation requirements of heavy load equipment, and the o...
