Abstract
A bio-fuel cell includes at least one bio-fuel cell element. The bio-fuel cell element includes an anode, a cathode, an anode container filled with the bio-fuel, a proton exchange membrane sandwiched between the anode and the cathode, and a guide plate. The cathode includes a catalyst layer. The catalyst layer includes a number of tube carriers having electron conductibility, a number of catalyst particles uniformly adsorbed on inner wall of each of the tube carriers, and proton conductor filled in each of the tube carriers. The tube carriers cooperatively define a number of reaction gas passages. One end of each of the tube carriers connects with the proton exchange membrane. The guide plate is disposed on a surface of the cathode away from the proton exchange membrane.
