Patent number: 9093690Abstract: The invention relates to a sensor fuel cell that can be activated by a first substance (O2) in its environment. The sensor fuel cell includes a catalytically active anode, a cathode that has a cathode surface at least partially exposed to the environment, and a proton-conductive membrane located between the anode and the cathode so as to convey protons through from the anode to the cathode. An anode surface of the anode is at least partially exposed to the environment for access of at least one second substance (H2) from the environment to the anode. Such a disposition enables access of a first reactant in the form for example of oxygen from the ambient air to the cathode, and additionally access of a second reactant in the form for example of hydrogen from the ambient air to the free surface of the anode.Type: GrantFiled: November 6, 2008Date of Patent: July 28, 2015Assignee: Micronas GmbHInventors: Gilbert Erdler, Holger Reinecke, Claas Mueller, Mirko Frank

Patent number: 8129861Abstract: A voltage supply has a plurality of voltage sources to supply output connections. To achieve closed-loop control of the output voltage at the output connections, a closed-loop control circuit is provided that has an actuating element for each voltage source, and each respective actuating element has a current path via which a connection of the respective voltage source can be connected to an output connection. Each actuating element has an actuating signal input for setting the electrical conductivity of its current path. The closed-loop control circuit has a closed-loop controller to which the output voltage and a desired voltage signal are supplied. When a deviation occurs between the output voltage and the desired voltage signal, the closed-loop controller interacts with at least one actuating signal input in order to reduce the deviation.Type: GrantFiled: October 21, 2009Date of Patent: March 6, 2012Assignee: Micronas GmbHInventors: Matthias Kuhl, Claas Müller, Yiannos Manoli, Gilbert Erdler
