Description

technical field [0001] The invention belongs to the technical field of proton exchange membrane fuel cells, in particular to an electroplating solution for preparing a Pt-Ru catalyst for a proton exchange membrane fuel cell, a preparation method for a Pt-Ru catalyst membrane and a proton exchange membrane fuel cell. Background technique [0002] A proton exchange membrane fuel cell (PEMFC) generates electricity directly through the chemical reaction of a fuel (such as natural gas, methanol, or pure hydrogen) between two electrodes separated by an electrolyte. The power generation efficiency of proton exchange membrane fuel fuel cells can reach 45%-60%. In addition to emitting a low ratio of carbon oxides, it has almost no other harmful emissions, has little environmental pollution, and has low temperature requirements. It is a clean and environmentally friendly new energy power generation system. [0003] Among them, direct methanol fuel cell (Direct Methanol Fuel Cell, DM...
