The invention discloses a fuel cell reactor device which is formed by sequentially stacking a plurality of bipolar plate assemblies and a plurality of membrane electrode assemblies. The membrane electrode assembly comprises an ion exchange membrane, a reduction catalyst and an oxidation catalyst; the ion exchange membrane is a non-metal film which can be penetrated by ions but cannot be penetrated by electrons; the reduction catalyst and the oxidation catalyst are both conductors and are respectively laid on the surfaces of the two sides of the ion exchange membrane in a continuous line shape to form a specific catalyst pattern, two-dimensional planarization is presented, and a three-phase interface is in an open layout. According to the fuel cell reactor device provided by the invention, the membrane electrode assembly is simple in structure, the fluid conveying resistance is greatly reduced, and the accessory consumption power is greatly reduced; the invention further provides a manufacturing method of the membrane electrode assembly, the process is simple, and the equipment cost is low. Therefore, the fuel cell reactor device is higher in system efficiency and lower in cost.
Description
technical field [0001] The invention relates to a fuel cell reactor device and a manufacturing method thereof, in particular to a membrane electrode assembly of a fuel cell reactor device and a manufacturing method thereof. Background technique [0002] The fuel cell reactor device is a device that converts chemical energy into electrical energy. It is composed of several sets of bipolar plate assemblies and several sets of membrane electrode assemblies stacked in sequence. The reducing agent and oxidant enter the fuel cell reactor device to complete the oxidation and reduction reactions. Output electric energy externally. [0003] Each MEA usually consists of an ion exchange membrane, an oxidation catalyst layer and a reduction catalyst layer separated on both sides of the ion exchange membrane, a reducing agent diffusion layer attached to the oxidation catalyst layer, and an oxidant diffusion layer attached to the reduction catalyst layer. Layer upon layer. [0004] The ...
