  • Method for controlling pressure
    Patent number: 10497954
    Abstract: A method for controlling the pressure on the cathode side of a fuel cell system is disclosed. The fuel cell system has at least one fuel cell, an air conveying device which is arranged on a common shaft with an expander, and a system bypass which connects the pressure-side outlet of the air delivery device to the pressure-side inlet of the expander via a system bypass line and a system bypass valve. The system bypass valve is opened in order to increase the pressure in the fuel cell.

  • Method for supplying air to a fuel cell
    Patent number: 9786936
    Abstract: A method for supplying air to a fuel cell (2), using a controllable air conveying device (7) which delivers an air mass flow for a cathode chamber (4) of the fuel cell (2), and using at least one air mass flow sensor (9, 18). The invention is characterized in that, for at least one location (19) in the air flow path which is situated at a distance from the at least one air mass flow sensor (9) in the flow direction, a computed estimate is made of the air mass flow present at that location.

  • METHOD FOR SUPPLYING AIR TO A FUEL CELL
    Publication number: 20150004514
    Abstract: A method for supplying air to a fuel cell (2) by means of a controllable air-conveying device that delivers an air mass flow for a cathode chamber (4) of the fuel cell (2). The air-conveying device (7) is adjusted to a specified value of a pressure (psoll) in the air line and/or to a specified value of a pressure loss (?psoll) across a component of the air line.
