A polymer-modified porous material, a membrane electrode, and applications thereof are disclosed. The polymer-modified porous material includes a porous material and a plurality of surface groups attached to the porous material; each of the surface groups includes a linking group and an adhesive group that are attached in sequence; the linking group has a structure represented by a structural unit I, wherein represents that O is linked to the porous material; the number of the structural units I in each of the surface groups is independent from each other; the total number n of moles of the structural units I in the polymer-modified porous material is 1,000-10,000; and the total number m of moles of the adhesive groups is 10-1,000, and n/m=10-1,000. The problem of serious self-discharge of existing membrane electrodes is alleviated.
