Problems solved by technology

[0005] Traditionally, when two fuel cell units are connected in series, a conductive bipolar plate (Bipolar plate) is used to connect the battery units in series through mechanical pressure and separate the cathode and anode fuels. However, the method of using bipolar plates often requires the introduction of larger fluid transport Components, for low-power or small-sized fuel cells, the combination of battery cells tends to be in a planar design, so the planar battery cell series connection will be a problem that must be overcome

Abstract

The invention discloses a planar fuel cell module which comprises a first collector layer combination, a second collector layer combination and a membrane electrode assembly combination between the first collector layer combination and the second collector layer combination. The membrane electrode assembly combination is composed of a plurality of membrane electrode assemblies, and the first collector layer combination and the second collector layer each comprises a plurality of collector layers. The first collector layer combination and the second collector layer combination are electricallyconnected in series by a plurality of series structures.

Description

technical field [0001] The invention relates to a fuel cell, in particular to a planar fuel cell module. Background technique [0002] Fuel Cell (Fuel Cell) is a power generation device that converts chemical energy into electrical energy. Compared with traditional power generation methods, fuel cells have the advantages of low pollution, low noise, high energy density, and high energy conversion efficiency. Future-looking clean energy, and its applicable scope includes various fields such as portable electronic products, household power generation systems, transportation tools, military equipment, space industry, and large-scale power generation systems. [0003] The operating principle of the fuel cell varies slightly depending on the type. Taking the Direct Methanol Fuel Cell (DMFC) as an example, the methanol aqueous solution is oxidized on the anode catalyst layer to generate hydrogen ions (H + ), electronics (e - ) and carbon dioxide (CO 2 ), where the hydrogen ions...
