Embodiment

[0040] Such as figure 1 The schematic diagram of the integrated reversible fuel cell system is shown. The system can realize forward hydrogen power generation, convert chemical energy into electrical energy, and can also realize reverse electrolysis of water to produce hydrogen, convert electrical energy into chemical energy, and perform forward power generation When hydrogen is produced in the reverse direction, there is no need to change the hardware structure such as the bipolar plate and membrane electrode forming the integrated reversible fuel cell stack 3 and the flow channel settings on the bipolar plate. The same fuel cell system is used in the forward and reverse processes. The whole system is simple and cost-saving.

[0041] The system mainly includes an integrated reversible fuel cell stack 3, a hydrogen circulation module, an oxygen circulation module and a water circulation module; Fluid inlet and outlet, the single cell includes a conductive plate and a membrane...

Abstract

The invention relates to an integrated reversible fuel cell system which comprises a hydrogen production power generation module formed by a fuel cell stack, a hydrogen circulation module, an oxygen circulation module and a water circulation module. The fuel cell stack is composed of a plurality of single cells which are stacked sequentially, a hydrogen inlet, a hydrogen outlet, an oxygen inlet, an oxygen outlet, a cooling fluid inlet and a cooling fluid outlet; each single cell is composed of a conductive plate and a membrane electrode; the hydrogen circulation module is connected with the hydrogen inlet and outlet of the fuel cell stack; the oxygen circulation module is connected with the oxygen inlet and outlet of the fuel cell stack; the water circulation module is connected with the cooling fluid inlet and outlet of the fuel cell stack; and in the system, power generation by the fuel cells is carried out in a forward process, and hydrogen production by electrolyzed water is carried out in a reverse process. Compared with the prior art, the integrated reversible fuel cell system has the advantages of being simple and compact in structure, lowering the cost, recycling water, hydrogen and oxygen raw materials, and integrated in management such as gas-water separation, and the like.

Description

technical field [0001] The invention relates to a fuel cell system, in particular to an integrated reversible fuel cell system. Background technique [0002] Hydrogen energy storage technology is considered to be an important support for the large-scale development of smart grid and renewable energy power generation, and has increasingly become the focus of energy technology innovation and industrial support in many countries. [0003] A fuel cell is a device that directly converts the chemical energy of hydrogen and oxygen into electrical energy through an electrode reaction. A fuel cell is usually composed of a plurality of battery cells, and each battery cell includes two electrodes (anode and cathode). separated by electrolyte elements and assembled in series with each other to form a fuel cell stack. By supplying each electrode with an appropriate reactant, ie fuel to one electrode and oxidant to the other, the electrochemical reaction is effected, creating a potential...
