A fuel cell includes at least one fuel cell element, which includes an anode, a cathode, a proton exchange membrane sandwiched between the anode and the cathode, a first flow guide plate, and a second flow guide plate. Each of the anode and the cathode includes a catalyst layer including a number of tube carriers having electron conductibility, a number of catalyst particles uniformly adsorbed on an inner wall of each of the tube carriers, and a proton conductor filled in each of the plurality of tube carriers. A first end of each of the tube carriers connects with the proton exchange membrane. The first flow guide plate is disposed on a surface of the anode away from the proton exchange membrane. The second flow guide plate is disposed on a surface of the cathode away from the proton exchange membrane.
