Patent number: 11444299Abstract: A method for the start preparation of a fuel cell system in a vehicle having a fuel cell and a system bypass where an air flow is conveyed by parts of the fuel cell system in order to dry the fuel cell. In a first temporal phase of the method, a larger part of the air flow is led through the fuel cell and a smaller part of the air flow is led through the system bypass, after which, in a second temporal phase, a larger part of the air flow is led through the system bypass and a smaller part of the air flow is led through the fuel cell.Type: GrantFiled: August 14, 2019Date of Patent: September 13, 2022Assignee: Cellcentric GMBH & CO. KGInventors: Pere Antoni Pastor Nigorra, Sven Schmalzriedt, Armin Muetschele

Patent number: 9614238Abstract: A fuel cell system includes at least one fuel cell and a humidifying device for humidifying a supply air flow flowing to a cathode chamber of the fuel cell by an exhaust air flow discharged from the cathode chamber of the fuel cell. The supply air flow and the exhaust air flow are separated from one another by water vapor-permeable membranes. An anode water separator, through which exhaust gas from an anode chamber of the fuel cell flows, is integrated into the humidifying device.Type: GrantFiled: July 21, 2012Date of Patent: April 4, 2017Assignee: Daimler AGInventors: Markus Handgraetinger, Armin Muetschele, Holger Richter, Miriam Runde

Publication number: 20140093797Abstract: A recirculation device for a fuel cell system includes a recirculation line connecting the outlet and inlet of the anode region of the fuel cell. The recirculation device includes a liquid separator situated in the area of the recirculation line and a discharge line having a discharge valve for liquid and/or gases. A bubble sensor for controlling the discharge valve is situated in the area of the discharge line. A method for discharging liquid and/or gases from a recirculation device opens and closes the discharge valve as a function of an event detected by the bubble sensor.Type: ApplicationFiled: May 4, 2012Publication date: April 3, 2014Applicant: Daimler AGInventor: Armin Muetschele

Publication number: 20110097633Abstract: In the operation of a fuel cell of a fuel cell system, water contained in the exhaust gas is stored in a water tank. The water tank has means for discharging the water in increments or portions. For example, the water can exit as droplets through the porous floor surface of the water tank, and be carried off by the driving wind while the vehicle is driving; or it can be collected at a wall of a water tank and fed into lines, returning it to the exhaust gas flow as droplets.Type: ApplicationFiled: March 7, 2009Publication date: April 28, 2011Applicant: Daimler AGInventors: Philip Anumu, Martin Gruber, Markus Grunenberg, Armin Muetschele, Stefan Reiff, Christian Safran, Vera Schorbach, Werner Schubert, Hans-Frieder Walz
