Abstract

The present invention provides a double-sided connector and a solid oxide stack, the double-sided connector comprising: a body having a first surface and a second surface; the plurality of first grooves are formed in the first surface, and the plurality of first grooves are arranged at intervals along the first direction; the plurality of second grooves are formed in the second surface, and the plurality of second grooves are communicated with one another. The air channel inlet and the air channel outlet are located on the two sides of the second grooves in the first direction, and the gas channel inlet and the gas channel outlet are located on the two sides of the first groove in the second direction. Based on the arrangement of the plurality of first grooves and the plurality of second grooves, the stack height of the stack is reduced, the volume occupation of the stack is reduced, and the heat loss surface area of the stack is reduced, so that the space utilization rate, the volume power ratio and the energy utilization efficiency of the stack are improved. And based on the gas channel inlet and outlet and the air channel inlet and outlet which are optimally designed, the gas leakage risk is reduced, and the utilization rate of gas and air is increased.
