Electric power conversion equipment (DC/DC converters)
Equipment to convert the electrical current and voltage characteristics of the input side (in this case, the photovoltaic cells), to the electrical current and voltage characteristics needed by the output side (the water electrolysis equipment). Assuming electrical conversion equipment currently available on the market were used in the equipment configuration developed in this trial, energy transport efficiency would be limited to about 80%.
 Concentrator photovoltaic cells
A type of photovoltaic cell that produces energy when strong sunlight concentrated through a lens is focused on small semiconductor elements made of high-quality semiconducting materials used in products such as lasers and LEDs. The semiconductor elements use three different materials that absorb different wavelengths of light, efficiently producing electricity from sunlight.
 Polymer electrolyte electrolysis equipment
Equipment that conducts electrolysis of water by joining catalyst electrodes to both sides of a solid polymer electrolyte membrane, supplying water to one side while applying direct current to both electrodes.
