    Abstract: A hydrogen system includes a compressor that includes an electrolyte membrane, an anode on a first primary surface of the electrolyte membrane, a cathode on a second primary surface of the electrolyte membrane, and a voltage applicator that applies a voltage between the anode and the cathode, the compressor producing compressed hydrogen by causing the voltage applicator to apply a voltage between the anode and the cathode to move hydrogen in hydrogen-containing-gas containing steam supplied to the anode to the cathode via the electrolyte membrane; a supply path through which the hydrogen-containing-gas containing steam to be supplied to the anode flows; a cooling mechanism disposed in the supply path; and a heat exchanger disposed in the supply path, the heat exchanger exchanging heat between the hydrogen-containing-gas flowing through the supply path upstream of the cooling mechanism and the hydrogen-containing-gas flowing through the supply path downstream of the cooling mechanism.

    Abstract: A reciprocating compressor of the disclosure includes a cylinder, a piston, a space for compressing gas, a discharge port for discharging the compressed gas from the space, a discharge valve, and a supplying port for supplying liquid that is different in kind from the gas. The cylinder has an axis extending in a direction of gravity. The piston is disposed to be reciprocable along the axis inside the cylinder. The space is constituted above the piston by being surrounded by the piston and an inner peripheral surface of the cylinder. The inner peripheral surface of the cylinder includes a straight portion and a throttle portion. The throttle portion is constituted such that an inner diameter of the cylinder decreases toward the discharge valve.

    Abstract: A CHP system includes a combustor as a heat source, a Rankine cycle apparatus, a second heat exchanger, and a thermal fluid flow path. The Rankine cycle apparatus includes, as an evaporator, a first heat exchanger that absorbs thermal energy from combustion gas (thermal fluid). The second heat exchanger absorbs thermal energy from the combustion gas and transfers the thermal energy to a heat medium. The first heat exchanger and the second heat exchanger are disposed in the thermal fluid flow path. The thermal fluid flow path includes a first flow path that allows the combustion gas to reach the first heat exchanger directly from the combustor and a second flow path that allows the combustion gas to reach the second heat exchanger directly from the combustor.

    Abstract: A Rankine cycle apparatus (1A) of the present disclosure includes a main circuit (10), a heat exchange portion (HX), a bypass flow path (20), a flow rate-adjusting mechanism (3), and a pair of temperature sensors (7A). The main circuit (10) is formed by an expander (11), a condenser (13), a pump (14), and an evaporator (15) that are circularly connected in this order. The heat exchange portion (HX) is located in the main circuit (10) at a position between an outlet of the expander (11) and an inlet of the pump (14). The bypass flow path (20) branches from the main circuit (10) at a position between an outlet of the evaporator (15) and an inlet of the expander (11), and joins to the main circuit (10) at a position between the outlet of the expander (11) and an inlet of the heat exchange portion (HX). The flow rate-adjusting mechanism (3) adjusts the flow rate of the working fluid in the bypass flow path (20). The pair of temperature sensors (7A) detects temperatures of the working fluid at two positions spaced from each other in a flow direction of the working fluid.
