Abstract
A high temperature steam electrolysis or fuel cell electric power generating facility, including at least two electrochemical reactors fluidly connected in series to each other by their cathode compartment(s). At least one heat exchanger is arranged between two reactors in series, a primary circuit of the heat exchanger being connected to an external heat source configured to provide heat to fluid(s) at an outlet of an upstream reactor prior to be introduced at an inlet of a downstream reactor.
Claims15
A high temperature steam electrolysis or fuel cell electric power generation facility, comprising:
- at least two electrochemical reactors;
- wherein each electrochemical reactor comprises at least one electrochemical unit cell, each cell including a cathode, an anode, and an electrolyte interposed between the cathode and the anode, at least one connecting element including at least one compartment for gas flow to the cathode, being arranged in electrical contact with the cathode of the unit cell, and at least one connecting element including at least one compartment for gas flow to the anode being arranged in electrical contact with the anode of the unit cell, and
- wherein both electrochemical reactors are fluidly connected in series to each other at least by one gas flow compartment,
- and further comprising at least one heat exchanger including a circuit fluidly connected in series to an outlet of one of the gas flow compartments of one of both reactors and to an inlet of one of the gas flow compartments of the other one of both reactors and including another circuit fluidly connected to a heat source external to the reactors.
