The invention discloses a proton exchange membrane fuel cell based on a hub runner structure, which comprises a cathode plate assembly and an anode plate assembly which are respectively sunken inwards in a hub shape to form hub runners and are oppositely arranged; the membrane electrode is arranged between the cathode plate assembly and the anode plate assembly in a spaced mode, the membrane electrode encloses hub flow channels in the cathode plate assembly and the anode plate assembly towards the two sides respectively, and the surface of the membrane electrode is exposed in the hub flow channels in the cathode plate assembly and the anode plate assembly; wherein a flow channel inlet is formed in the middle of the hub flow channel, and a flow channel outlet is formed in the rim part of the hub flow channel. The pressure drop of the wheel hub flow channel of the battery is good, so that reaction gas is distributed more uniformly, the flowing smoothness of the flow channel is improved, liquid water discharge i
