Abstract

The invention discloses an integrated cell, an integrated cell stack including the integrated cell and an integrated cell system. The integrated cell comprises an electrolytic cell for generating hydrogen and oxygen, and a fuel cell for generating electricity by the hydrogen and oxygen, wherein the fuel cell and the electrolytic cell share a collector plate and receive the hydrogen and oxygen generated by the electrolytic cell. According to the invention, the electrolytic cell and the fuel cell are integrally arranged to form the integrated cell; the number of the collector plates used is reduced; the cost is greatly saved; the integration is higher after integral arrangement; the management and maintenance of the integrated cell are facilitated; the reliability is enhanced in the process of conveying the hydrogen generated by the electrolytic cell to the fuel cell to generate electricity by the fuel cell at short range; a complicated process of purifying the air when the air is utilized is avoided by utilization of the oxygen, and output voltage of the cell is further improved by utilizing pure oxygen as reaction gas.

Description

technical field [0001] The invention relates to the field of batteries, in particular to an integrated battery, an integrated battery stack including the same, and an integrated battery system. Background technique [0002] When proton exchange membrane fuel cells are used in backup power or distributed power stations, the source of hydrogen needs to be solved. Generally, high-pressure hydrogen storage is used. However, the sustainability of its discharge is limited by the scale of the hydrogen storage device, and hydrogen fuel needs to be replenished regularly. In addition, there are other methods for providing hydrogen fuel: Chinese patent application number 01120272.6 uses a reformer to convert hydrogen-rich fuel into hydrogen for fuel cells as fuel, but there are the following problems, the reformer needs to consume additional electricity And cause heat and energy loss, the reformer needs to desulfurize and remove carbon monoxide, making its system extremely complex and...
