The flat plate type high temperature solid oxide electrolytic cell stack is generally formed by stacking a plurality of electrolytic cell units in series, and in order to separate hydrogen and oxygen generated between two adjacent electrolytic cells, a separator is required to be placed between two cells, and simultaneously, the cathode of one cell and the anode of the other cell are connected, and the separator is called a connector. The connector serves as one of the key components in the high temperature solid oxide cell stack, which functions to transport electrons between adjacent single cell units and to divide the cathode side and anode side gases. The gas flow distribution device can distribute gas flow in and out, provide a channel for gas to flow on two sides, output gas on the cathode side and gas on the anode side, participate in electrochemical reaction, remove products of the electrochemical reaction and ensure that the electrochemical reaction is continuously carried out.
The gas inlet and outlet on the existing connector are generally designed by uniformly distributing a plurality of small holes, and the design of the small holes increases the processing procedure, improves the processing cost of the connector, and the gas flow channel is not directly communicated with the gas inlet and outlet, so that the gas inlet and outlet efficiency is low, and the gas utilization rate and the electrochemical reaction rate are reduced.
