  • Patent number: 11621176
    Abstract: In a substrate processing apparatus (1), an enlarged sealed space (100) is formed by bringing a cup part (161) that forms a lateral space (160) around the outer periphery of a chamber (12) into contact with a chamber lid part (122) separated from a chamber body (121). A scan nozzle (188) is attached to the cup part (161) in the lateral space (160) and supplies a chemical solution onto a substrate after moving to above the substrate through an annular opening (81). During processing for cleaning the substrate and processing for drying the substrate, the scan nozzle (188) is housed in the lateral space (160) and an upper opening of the chamber body (121) is closed by the chamber lid part (122) to isolate the chamber space (120) from the lateral space (160) and seal the chamber space (120). Thus, the chamber space (120) can be isolated from the scan nozzle (188). This consequently prevents a mist or the like of the chemical solution supplied from the scan nozzle (188) from adhering to the substrate.

  • Patent number: 11114681
    Abstract: The fuel cell system performs prevention control for preventing an anode gas detector from erroneously detecting anode gas discharged from an exhaust port as leakage of anode gas from an anode gas flow path, when at least one of (i) a flow rate proportion, found by dividing a measured flow rate of cathode gas by an assumed flow rate of the cathode gas, is smaller than a predetermined flow rate proportion threshold, (ii) a pressure proportion, found by dividing a measured gas pressure by an assumed gas pressure, is larger than a predetermined pressure proportion threshold, and (iii) a voltage proportion, found by dividing a measured voltage of the fuel cell by an assumed voltage of the fuel cell, is smaller than a predetermined voltage proportion threshold, is satisfied. This prevents the anode gas detector from erroneous detection as leakage of anode gas.

  • Patent number: 11075393
    Abstract: A fuel cell system mounted in a mobile object is equipped with a bypass flow passage that establishes communication between an air compressor and an exhaust gas flow passage, and a valve that adjusts an amount of air supplied to the bypass flow passage. A control unit performs a process for increasing a flow rate of air caused to flow through the bypass flow passage, by controlling a drive amount of the air compressor and the opening degree of the valve, when an outside air temperature is equal to or lower than a threshold and a speed of the mobile object is equal to or lower than a determination speed. In the process, a flow rate of air at a first temperature that is lower than a second temperature that is equal to or lower than the threshold is larger than a flow rate of air at the second temperature.
