The invention provides a microchannel equipped micro direct methanol fuel cell and a microchannel treatment method. Specifically, a battery comprises a cathode end plate, a cathode collector plate, aproton exchange membrane, an anode collector plate, an anode end plate and a fuel chamber. The cathode end plate is in connection with the cathode collector plate, the anode end plate is in connectionwith the anode collector plate, and the anode collector plate and the cathode collector plate are in power connection so as to form a loop. The fuel chamber has a liquid storage cavity, the proton exchange membrane is sandwiched between the cathode collector plate and the anode collector plate, and is corresponding to the position of the liquid storage cavity. A through slot is disposed on the anode end plate at a position corresponding to the liquid storage cavity, and one side of the anode end plate facing the anode collector plate is equipped with at least one super-hydrophobic microchannel that communicates the through slot with the edge of the cathode end plate and is used for removing carbon dioxide gas. The microchannel equipped micro direct methanol fuel cell provided by the invention enables discharge of carbon dioxide gas directly from the side of the anode end plate, and reduces or even completely prevents carbon dioxide gas from entering the flow field of the anode end plate, thereby improving the methanol mass transfer ability of the anode in the battery.
