Channeled electrodes and method of making
There is disclosed a method of making an electrode for an electrochemical reactor including the steps of providing a template and depositing electrode material such that the electrode material is in contact with the template. This template is provided in a form that produces channels in the electrode material. There is also disclosed an electrode for an electrochemical reactor which includes electrode material and a template, with the template occupying channels in the electrode material.
FUEL CELL SYSTEM AND METHOD FOR CONTROLLING FUEL CELL SYSTEM
A fuel cell system according to the present disclosure includes: a solid oxide fuel cell that produces electricity from an electrochemical reaction by using a fuel and air and that includes a membrane electrode assembly including a proton-conductive electrolyte membrane, a cathode disposed on a first main surface of the electrolyte membrane, and an anode disposed on a second main surface of the electrolyte membrane; and a controller. In the operation stop process for stopping operation of the fuel cell system, the controller is configured to control supply of the fuel at a higher flow rate than the flow rate of the fuel consumed in the solid oxide fuel cell in an open circuit state.
Cartridge for firing
The present invention relates to a firing cartridge, and more particularly, to a firing cartridge in which multiple slit grooves are formed in lateral portions positioned between an upper end portion and a lower end portion, and solid fuel cell electrodes are inserted into the slit grooves, such that the number of cells, which may be fired at the same time, is increased, and thus productivity of a solid fuel cell may be improved.

FUEL CELL AND FUEL CELL SYSTEM FOR AN AIRCRAFT
In order to improve usability of hybrid or fully electric aircraft, a fuel cell having improved efficiency and increased volume/weight specific energy density is provided. The fuel cell has a self-supporting membrane structure that is formed as a triply periodic level surface, which separates a first cavity supplied with gaseous fuel from a second cavity supplied with gaseous oxidizer in a gas-sealed manner while connecting the cavities in an ion-conductive manner.
Cell unit
A cell unit CU includes a cell structure 1, a metal support plate 2 disposed on one side surface of the cell structure 1, and a frame 3 holding an outer peripheral part of the support plate 2. The cell structure 1 has a lamination of an anode electrode layer 4, an electrolyte layer 5, and a cathode electrode layer 6, in this order. The frame 3 includes a displacement guide 7 at least on one side surface of the frame 3. The displacement guide 7 has a coefficient of thermal expansion that is different from that of the frame 3 and is configured to make the frame 3 curve so that the cell structure 1 is concaved in accompany with thermal expansion. In the cell unit CU, a risk of concentration of tensile stress on the electrolyte layer 5 at the time of thermal expansion during operation is removed without reducing the strength of the frame 3, whereby occurrence of a crack and the like in the electrolyte layer 5 can be prevented beforehand.
