摘要： Methods for forming a metal oxide electrolyte improve ionic conductivity. Some of those methods involve applying a first metal compound to a substrate, converting that metal compound to a metal oxide, applying a different metal compound to the metal oxide, and converting the different metal compound to form a second metal oxide. Electrolytes so formed can be used in solid oxide fuel cells, electrolyzers, and sensors, among other applications.

摘要： A bipolar plate assembly includes a first frame member, a second frame member, and a membrane electrode assembly. The first frame member has a first side and a second side. The first side has a first side protuberance. The second frame member includes a first side and a second side. The second side has a second side recess. The membrane electrode assembly has an anode plate and a cathode plate. A portion of the membrane electrode assembly is disposed between the first frame member and the second frame member. The portion of the membrane electrode assembly has a juxtaposition of the anode plate and the cathode plate. The first side protuberance of the first frame member deforms the portion of the membrane electrode assembly into the second side recess of the second frame member.

摘要： The invention relates to a single corrugated fuel cell and a cell stack. The single cell comprises an anode plate, a cathode plate, and a membrane electrode assembly; the anode plate is of a corrugated structure and a plurality of anode channels and anode ribs are arranged on the anode plate in parallel; the cathode plate is of a corrugated structure engaged with the anode plate and a plurality of cathode channels and cathode ribs are arranged on the cathode plate in parallel; the membrane electrode assembly is arranged between the anode plate and the cathode plate. The single cell presents a corrugated structure in a width direction of the channel. A plurality of single cells are stacked in sequence to form a fuel cell stack. Compared with the prior art, the invention significantly increases the reaction area per unit volume of the fuel cell through the corrugated structural design, thereby improving the power density of the fuel cell. In addition, the present invention has little change to the existing processing and manufacturing technology, and thus has high production feasibility.
