An energy management system is provided with a fuel synthesizing apparatus, a power generation apparatus, a COrecovering unit, a compressor, a COstorage unit, a COpressure reducing unit and a heat recovery unit. The fuel synthesizing apparatus generates hydrocarbon from HO and COusing externally supplied power. The power generation apparatus generates power using the hydrocarbon. The COrecovering unit recovers COfrom an exhaust gas exhausted from the power generation apparatus during a power generation. The compressor compresses the recovered CO. The COstorage unit stores the COcompressed by the compressor. The COpressure reducing unit depressurizes the COstored in the COstorage unit in order to supply the fuel synthesizing apparatus therewith. The heat recovery unit recovers heat from the CO, the heat having been stored in the COwhen compressed or depressurized.

Energy management system

An energy conversion system includes a fuel synthesis device, an HO supply unit, a COsupply unit, and a supply control unit. The fuel synthesis device includes an electrolyte, and a pair of electrodes provided on both sides of the electrolyte. The HO supply unit supplies HO to the fuel synthesis device. The COsupply unit supplies COto the fuel synthesis device. The supply control unit controls a supply of HO and a supply of CO. The fuel synthesis device electrolyzes HO and COusing external electric power, and synthesizes a hydrocarbon using Hand CO generated by electrolysis. The supply control unit starts the supply of HO to the fuel synthesis device by the HO supply unit after the supply of COto the fuel synthesis device by the COsupply unit is started.

Energy conversion system

A gas sensor includes a solid electrolyte substrate that has oxygen-ion conductivity, and a counter plate, made of ceramic, that is arranged so as to face a first surface of the solid electrolyte substrate. The gas sensor further includes a first spacer, made of ceramic, that is held between the counter plate and the solid electrolyte substrate, a heater substrate, made of ceramic, that is arranged so as to face a second surface of the solid electrolyte substrate, and a second spacer, made of ceramic, that is held between the heater substrate and the solid electrolyte substrate. Of the counter plate, the sintered density of an inside portion that comes in contact with a measurement-gas chamber is 0.8 to 5.0% lower than the sintered density of an outside portion that comes in contact with the first spacer.
