This invention discloses a sulfonic acid-based polyethylene oxide solid proton exchange membrane, its preparation method, and its application. The solid proton exchange membrane includes a porous support layer and a sulfonic acid-based polyethylene oxide proton conductor layer loaded on its surface and / or within its pores. The proton conductor layer is formed by reacting or compounding polyethylene oxide or a polymer containing polyethylene oxide segments with an acidic reagent containing sulfonic acid groups or capable of introducing sulfonic acid groups, and contains fixed acidic proton sites and ether oxygen segments.
