Abstract
A small and high-density biofuel cell capable of easily supplying fuel; and an electronic apparatus are provided. The biofuel cell is formed using a stack in which two power generating bodies that include at least a pair of electrodes and a separator are stacked through a gas diffusion layer through which only gas is permeable, the electrodes forming an anode and a cathode and having at least one surface on which an oxidoreductase is present, the separator being arranged between the electrodes and including a proton permeable membrane. In addition, cathode-side surfaces of the respective power generating bodies of the stack are arranged in contact with the gas diffusion layer. This biofuel cell is mounted on the electronic apparatus.
