Abstract: An electrochemical reaction cell stack includes an electrochemical reaction block including three or more electrochemical reaction units arranged in a first direction. The electrochemical reaction block includes a gas introduction flow passage, a gas discharge flow passage, and a gas transfer flow passage. An upstream electrochemical reaction unit includes an upstream introduction communication passage for connecting an upstream anode chamber to the gas introduction flow passage, and an upstream discharge communication passage for connecting the upstream anode chamber to the gas transfer flow passage. Similarly, a downstream electrochemical reaction unit includes a downstream introduction communication passage and a downstream discharge communication passage. In each of two or more downstream electrochemical reaction units, the total volume of the downstream introduction communication passage and the downstream discharge communication passage is smaller than the total volume of the upstream introduction communication passage and the upstream discharge communication passage.

Abstract: A planar fuel cell apparatus (1) characterized in that, as viewed in a stacking direction, a first rectilinear line which connects a centroid Cfi of fuel gas inlets and a centroid Cfo of fuel gas outlets, and a second rectilinear line which connects a centroid Cai of oxidizer gas inlets and a centroid Cao of oxidizer gas outlets cross each other. That is, the planar fuel cell apparatus employs cross-flow design in which a fuel gas flow channel and an oxidizer gas flow channel cross each other. In the planar fuel cell apparatus of the cross-flow design, as viewed in the stacking direction, the centroid Cfo of the fuel gas outlets is located closer to the centroid Cai of the oxidizer gas inlets than to the centroid Cao of the oxidizer gas outlets.

Abstract: Provided is an exhalation sensor that utilizes heat effectively and can operate with low power consumption. The exhalation sensor has a surface layer on its surface that faces a sensor main body, and the performance of the surface layer to reflect radiant heat is higher than that of a housing. Specifically the radiant heat reflectivity of the surface layer is higher than that of the housing. Therefore, the surface layer can reflect radiant heat emitted from the sensor main body more efficiently than the housing. The radiant heat emitted from the sensor main body is less likely to escape to the outside of the housing, so that the heat generated by a heater of the sensor main body can be efficiently stored within the housing. This can reduce the power consumed by the heater to heat a conversion section and a sensing section to their operating temperatures.

Abstract: Disclosed is a gas sensor including: a wiring board; a sensor element mounted on the wiring board and electrically connected to the wiring board by conductive members; a casing installing the sensor element and formed with inlet and outlet ports; and a pretreatment unit configured to perform pretreatment on a measurement gas and feed the measurement gas to the inlet port. The inlet and outlet ports are located outward and upward of the sensor element. A protrusion is provided protruding toward the inside of the casing so as to narrow a flow path from the inlet port to the outlet port. A height from the sensor element to a distal end of the protrusion is lower than heights from the sensor element to the inlet and outlet ports. The protrusion is disposed more inside than respective top portions of the conductive members without being in contact with the conductive members.

Abstract: A gas sensor including an adjustment unit having a conversion element for converting a gas component contained in exhaled breath introduced into a first chamber to a particular component, a sensor unit having a second chamber and including a detection element, a ceramic wiring board electrically connected to the detection element, and a single heater for heating the conversion element and the detection element. The ceramic wiring board has an opening, and a ceramic thin plate is stacked on the ceramic wiring board to cover the opening. The ceramic thin plate partially constitutes the adjustment unit and the sensor unit and separates the first chamber and the second chamber from each other. The adjustment unit, the sensor unit, and the heater are integrated in such a manner that the adjustment unit and the sensor unit are thermally coupled through the ceramic thin plate.
