  • Patent number: 9912000
    Abstract: In the case in which a fuel cell has a structure in which a cathode (2) and an anode (1) are opposed with the intermediary of an electrolyte layer (3) and the cathode (2) is formed of an electrode to which an oxygen reductase and so on is immobilized and this electrode has pores inside, at least part of the surface of this electrode is rendered water repellent. For example, the surface of the electrode is rendered water repellent by forming a water-repellent agent on the surface of this electrode. Thereby, in the case in which the cathode is formed of an electrode to which an enzyme is immobilized and this electrode has pores inside, a fuel cell that can stably achieve a high current value by optimization of the amount of water contained in the cathode and a manufacturing method thereof are provided.
