The invention relates to the technical field of electrolysis water catalysis, in particular to a low-energy-consumption membrane electrode which is prepared from a low-energy-consumption catalytic layer and a perfluorosulfonic acid proton exchange membrane, a mixture with a bubble dredging function is introduced into the structure of the low-energy-consumption catalytic layer, and both the low-energy-consumption catalytic layer and the perfluorosulfonic acid proton exchange membrane in the mixture have the hydrophilic property; the problem that in the prior art, an additive and a perfluorosulfonic acid polymer are poor in compatibility is solved, the catalyst layer has a good hydrophilic contact angle, then the anti-foaming performance of the catalyst layer is improved, and the electrolysis energy consumption of the catalyst layer is effectively reduced; the amino-functionalized metal oxide and the perfluorinated sulfonic acid resin contained in the mixture with the bubble dredging function both have high mol
