A heat exchanger can be integrated into an interconnector that can be used in both a SOFC fuel cell and an EHT electrolyser, which allows a heat-transfer fluid different from that in the reactive and drainage gas circuits to be circulated from the inlet of the reactor, thereby allowing the best possible management of the exothermic operating modes of the SOFC cell and the exothermic or endothermic operating modes of the EHT electrolyser and the SOFC cell, especially in the absence of current for the latter.

A plate heat exchanger can reduce thermal contact between a second fluid (water and a third fluid (low-temperature, low-pressure two-phase refrigerant) to enhance thermal efficiency. A plate heat exchanger (1b) includes a heat transfer plate group (102a) that performs heat exchange between a first fluid of high-temperature, high-pressure gas refrigerant and a second fluid of a heating target fluid; and a heat transfer plate group (102b) that performs heat exchange between a first fluid of low-temperature, high-pressure liquid refrigerant and a third fluid of low-temperature, low-pressure two-phase liquid refrigerant. The heat transfer plate group (102a) forms refrigerant channels including a stack of plates, has a configuration that a flow of the first fluid of high-temperature, high-pressure gas refrigerant and a flow of the second fluid are alternately aligned in the refrigerant channels, and causes the second fluid to flow in the outermost refrigerant channel.

A heat transfer plate comprises a first end area, a heat transfer area and a second end area along a longitudinal center axis of the plate which divides the plate into first and second halves delimited by first and second long sides respectively.

The distribution area has a distribution pattern of projections and depressions, the transition area has a transition pattern of projections and depressions, and the heat transfer area has a heat transfer pattern of projections and depressions. An imaginary straight line extends between two end points of each transition projection with an angle relative to the longitudinal center axis. The angle varies between the transition projections and increases from the first long side to the second long side.

A bypass passage fluidly interconnects the incoming fluid stream and the outgoing fluid stream.

A heat exchanger plate has a vertical center axis dividing the plate into a left and a right half delimited by a first and second long side, respectively. A horizontal center axis divides the plate into an upper and a lower half delimited by a first and second short side, respectively. The plate includes a port hole with a reference point that coincides with a center point of a biggest imaginary circle that can be fitted into the port hole. The port hole is arranged within the left half and the upper half.
