RECIRCULATION ARRANGEMENT AND METHOD FOR A HIGH TEMPERATURE CELL SYSTEM

CONVION OY, Espoo (FI)

1. A recirculation arrangement for a high temperature fuel cell system or electrolysis cell system, each cell in the system having an anode, a cathode, and an electrolyte between the anode and the cathode, the recirculation arrangement comprising:at least one ejector for recirculating a fraction of gas exhausted from the anode and for accomplishing a desired flow rate of the recirculated flow, the ejector having at least one nozzle;
means for providing at least one primary feedstock fluid to said nozzle of the ejector, which nozzle has a convergent-divergent flow channel through which the at least one primary feedstock fluid will expand from an initial higher pressure to a lower pressure;
means for providing at least one supplementary fluid to said nozzle of the ejector, the supplementary fluid constituting a majority of a total flow supplied to the nozzle at startup of the system;
means for regulating a respective ratio of at least part of the fluids of the ejector to maintain a desired motive flow and pressure at the nozzle of said ejector in order to accomplish the desired recirculated flow rate; and
means for cutting off the supplementary fluid when a level of system loading is such that the primary feedstock fluid alone maintains the desired motive flow and pressure at an ejector inlet,
wherein the at least one ejector comprises a supersonic ejector,
wherein in the supersonic ejector, motive flow expands in a series of supersonic shocks assisting in mixture of the supplementary fluid with the at least one primary feedstock fluid, the at least one supplementary fluid is water,
wherein an oxygen to-carbon ratio of a mixture of primary and supplementary fluids supplied to the nozzle of the ejector is above a carbon forming threshold when fuel cells are not loaded, and
wherein the flow in said nozzle reaches speed of sound whenever at least one primary feedstock is supplied.
