An apparatus can include a housing, a plurality of electrochemical devices disposed within the housing, and a heat exchanger disposed within the housing. The heat exchanger can be faced with an oxidant-containing gas outlet surface of at least one of the plurality of electrochemical devices. The electrochemical devices can include a stack of solid oxide fuel cells, a battery, or a solid oxide electrolyzer cell.

Apparatus including electrochemical devices and heat exchanger

A solid oxide fuel cell with a dense barrier layer formed at or near the outer surface of the top and/or bottom electrode layers in a fuel cell stack. The dense barrier layer (DBL) acts as a seal to prevent gas in the electrode layer (either air in a cathode layer or fuel gas in an anode layer) from leaking out of the stack though the outer surface of the outermost electrode layers. The use of a DBL with porous outer electrode layers reduces the amount of gas escaping the stack and minimizes the chances for leak-induced problems ranging from decreases in performance to catastrophic stack failure.

Embodiments of the present disclosure relate to a hot press and methods of using the hot press. In an embodiment, the hot press can include a pressing element including a flared body. In another embodiment, the hot press can include a compression surface. The compression surface can include a first layer including a monocrystalline material and a second layer including a polycrystalline material, wherein the monocrystalline material and the polycrystalline material include a same primary compound. In a further embodiment, a sample including more than one layer of ceramic oxide material can be hot pressed without a die.
