    摘要: The operation of relative humidity sensors made from cobalt oxide on a non-conductive ceramic substrate is improved by heating the sensor for a short period to a high temperature in a reducing atmosphere. This reduces the specific resistance of the device. With a lower resistivity, it is possible to reduce the size of the sensor to the point where it can be included along with a semiconductive device in standard hermetic packages. This makes possible the continuous, one-line monitoring of hermeticity for the life of the circuit without the necessity fo applying a load to the circuit.

    摘要: Oxygen sensor specifically adapted for use in an industrial air/fuel control system provides an ability to measure actual oxygen content quantitatively in industrial situations where off-stoichiometric air/fuel control is desired. The sensor is quite simple and is easy to use since it provides accurate reproducible readings from sensor to sensor and for long periods. The leads to the solid electrolyte disc are of the same material as the electrodes and extend to the remote end of the sensor so as to eliminate dissimilar material junctions. Felted ceramic discs applied to the wet paste electrodes before firing serve to filter the gases contacting the sensor and act as wicks for permitting uniform dispersion of chloroplatinic acid to the paste electrodes.

    摘要: A core construction for a fuel cell is disclosed having both parallel and cross flow passageways for the fuel and the oxidant gases. Each core passageway is defined by electrolyte and interconnect walls. Each electrolyte wall consists of cathode and anode materials sandwiching an electrolyte material. Each interconnect wall is formed as a sheet of inert support material having therein spaced small plugs of interconnect material, where cathode and anode materials are formed as layers on opposite sides of each sheet and are electrically connected together by the interconnect material plugs. Each interconnect wall in a wavy shape is connected along spaced generally parallel line-like contact areas between corresponding spaced pairs of generally parallel electrolyte walls, operable to define one tier of generally parallel flow passageways for the fuel and oxidant gases. Alternate tiers are arranged to have the passageways disposed normal to one another. Solid mechanical connection of the interconnect walls of adjacent tiers to the opposite sides of the common electrolyte wall therebetween is only at spaced point-like contact areas, 90 where the previously mentioned line-like contact areas cross one another.
