Abstract

The invention relates to a proton exchange membrane fuel cell, specifically to a modular design method for the proton exchange membrane fuel cell, which comprises two or more than two stacks and distributing plates, the distributing plates are successively composed by distributing plate cover plates, distributing plates for oxidizing agent and cooling agent, separating plates, fuel agent distributing plates, as well as fuel agent cover plates, two sides are separately arranged with fluid access channels, and two sides of the distributing plates form one group or more than one group of fluid access channels for the distributing plates; the access channels for oxidizing agent, cooling agent, and fuel agent of the distributing plates are separately connected with the access channels for or oxidizing agent, cooling agent, and fuel agent on the stacks; the inlet distributing channels and the outlet distributing channels for oxidizing agent, cooling agent, and fuel agent of the distributingplates are separately connected with corresponding external fluid conduit lines; the invention amends connection methods for a plurality of fuel cell groups, perfects gas distribution uniformity, improves volume fraction power, and simplifies system components, which is suitable for commercialization development needs of fuel cell.

Description

technical field [0001] The invention relates to a proton exchange membrane fuel cell, in particular to a modular design method for a proton exchange membrane fuel cell. Through the use of a distribution plate, a plurality of fuel cell groups are distributed at both ends of the distribution plate like building blocks, so that The fuel cell system is more compact and rationally arranged. By changing the power of a single fuel cell stack, the fuel cell modules can meet different output power requirements. Through the modular design of the fuel cell, not only the volume specific power of the whole system is improved, but also the system components are simplified, which is suitable for the commercial development of the fuel cell. Background technique [0002] At present, the high-power fuel cell stacks used in fuel cell engines are composed of multiple battery packs connected in series and parallel through external pipelines, which not only requires a lot of work in terms of pip...
