Abstract: A high-temperature fuel cell system includes a fuel cell that includes an anode and a cathode and that generates power by using a fuel gas and an oxidant gas, a fuel-gas path along which the fuel gas flows, an oxidant-gas path along which the oxidant gas flows, an anode-off-gas path along which an anode off-gas flows, a cathode-off-gas path along which a cathode off-gas flows, a combustion space in communication with the anode-off-gas path and the cathode-off-gas path and in which the anode off-gas and the cathode off-gas are burned, a flue-gas path along which a flue gas flows, a cathode-off-gas branch portion disposed on the cathode-off-gas path between the combustion space and the cathode and at which some of the cathode off-gas is branched from the cathode-off-gas path, and a first heat exchanger that enables heat exchange between the oxidant gas, the flue gas, and the cathode off-gas.

Abstract: The present disclosure is to provide a multi-junction light energy conversion element including a material having a band gap suitable for a light energy conversion layer located upstream in an incidence direction of light. The present disclosure provides a light energy conversion element, comprising a first light energy conversion layer containing SrZn2N2 and a second light energy conversion layer containing an light energy conversion material. The light energy conversion material has a narrower band gap than the SrZn2N2.

Abstract: A fuel cell system includes a reformer, a raw-material supplier, a desulfurizer, a flow controller, a vapor supplier, a fuel cell, a combustor, and a controller. After the raw-material supplier supplies a raw material at the startup of the fuel cell system, the controller causes the combustor to combust the raw material exhausted as off-gas from the fuel cell, subsequently causes the flow controller to allow gas exhausted from the reformer to flow through a recycle gas passage, and thereafter causes the vapor supplier to supply vapor, or the controller causes the flow controller to allow the gas exhausted from the reformer to flow through the recycle gas passage, subsequently causes the combustor to combust the raw material exhausted as the off-gas from the fuel cell, and thereafter causes the vapor supplier to supply the vapor.
