摘要： A light-driven fuel cell includes a cathode, an anode, and a proton-permeable membrane between the anode and the cathode. The anode includes a photocatalyst for anaerobic methane oxidation reaction, and when the anode is supplied with methane and water and is irradiated with light, methanol, protons and electrons are generated by anaerobic methane oxidation reaction from the methane and the water supplied to the anode; the protons pass through the proton-permeable membrane and move to the cathode; and the electrons move to the cathode via an external circuit. The cathode includes a photocatalyst for aerobic methane oxidation reaction, and when the cathode is supplied with methane and oxygen and is irradiated with light, methanol and water are generated by aerobic methane oxidation reaction from the methane and the oxygen supplied to the cathode and the protons and the electrons moved from the anode.

摘要： The present invention is to provide a photocatalyst electrode less likely to suffer from peeling of hematite-based crystal particles from a substrate and having higher catalytic activity than ever before. A method for producing a photocatalyst electrode includes: an in-process particle of heating a raw material solution to form in-process particles, the raw material solution including a raw material solvent and a hematite raw material dispersed therein, the in-process particle forming step including heating the raw material solution in a closed vessel for more than 12 hours; and a burning step of burning the in-process particles. In this way, a photocatalyst electrode with high catalytic activity can be produced.

摘要： An electrochemical cell has a first reaction chamber having a first electrode, a second reaction chamber having a second electrode, a membrane-electrode assembly having an ion-exchange membrane, and a photovoltaic system for absorbing solar energy and producing an output voltage between a first output terminal selectively couplable to the first electrode and a second output terminal selectively couplable to the second electrode. The ratio between a photosensitive area of the photovoltaic system and an active area of the first and second electrodes is less than or equal to fifty. A plurality of photovoltaic cells is selectively couplable between the first and second output terminals. An electronic control unit couples the photovoltaic cells as a function of at least one among one or more user-settable parameters, one or more signals received from an external control unit, one or more signals received from one or more sensors included in the electrochemical cell.
