Abstract

The invention relates to a reversible fuel cell, in particular to an integrated reversible fuel cell energy system which comprises an integrated reversible fuel cell subsystem, a lithium battery auxiliary starting subsystem, a solar electrolysis energy supply subsystem and a hydrogen storage subsystem. The integrated reversible fuel cell subsystem consists of an integrated reversible fuel cell stack, a hydrogen circulation subsystem, an air circulation subsystem, a cooling water circulation subsystem and an electrolyzed water circulation subsystem; and the system comprises a power generation mode and an electrolysis mode. Compared with the prior art, cyclic utilization of hydrogen is realized, and hydrogen can be efficiently utilized, produced and stored through cooperation of the integrated reversible fuel cell subsystem, the lithium battery auxiliary starting subsystem and the solar electrolysis energy supply subsystem, so that the endurance time of the system is prolonged, and the energy utilization efficiency of the system is improved.

Description

technical field [0001] The invention relates to a reversible fuel cell, in particular to an integrated reversible fuel cell energy system. Background technique [0002] Hydrogen energy, because of its high energy storage density and non-polluting characteristics, is expected to become a new energy source that can replace traditional fossil energy sources such as oil and coal. The integrated reversible fuel cell (Unitized Regenerative Fuel Cell, URFC) is a means of efficient utilization of hydrogen energy. It has two functional modes of electrolysis and power generation. Hydrogen has broad application prospects in energy systems on mobile platforms, such as electric vehicles, drones, and power grid peak regulation. [0003] Chinese patent CN106784960B discloses an integrated reversible fuel cell subsystem, including a hydrogen production power generation module composed of a fuel cell stack, a hydrogen circulation module, an oxygen circulation module and a water circulation ...
