Patent number: 10581098Abstract: The invention relates to a starting method for a fuel cell system (100), particularly for an air/air start of the fuel cell system (100). The method enables the reduction of damaging half-cell voltages in the fuel cell stack (10) through voltage limitation by means of a DC voltage converter. The homogeneous flushing of the fuel cell stack (10) required for this takes place by means of introduction of an anode operating medium into an anode inlet channel (17) of the otherwise sealed fuel cell stack (10) until a predetermined pressure is reached and flushing of the active areas of the fuel cells (11) of the stack (10) after said pressure is reached through opening of an anode discharge adjusting aid (26), preferably arranged in an exhaust coupling (29) connecting the anode exhaust line (22) and the cathode exhaust line (31).Type: GrantFiled: June 6, 2017Date of Patent: March 3, 2020Assignees: VOLKSWAGEN AG, AUDI AGInventors: Ingmar Hartung, Maren Ramona Kirchhoff, Martin Arendt, Heiko Turner

Patent number: 9365937Abstract: A system providing selective spin modification and reaction in an electrolytic cell. An electrolytic cell is coupled to a magnet that provides a level-splitting magnetic field in a region of electrolyte adjacent to a working electrode, thus establishing a spin resonance for an unpaired electron associated with a chemical species in the region of electrolyte adjacent to the working electrode. The working electrode carries an excitation current produced by a switching source or amplifier. The excitation current produces an alternating magnetic field adjacent to the working electrode that alters the spin state population density for the unpaired electron associated with a chemical species within the electrolyte, thereby enhancing or inhibiting the reaction of the chemical species during subsequent electrolysis.Type: GrantFiled: August 14, 2013Date of Patent: June 14, 2016Inventor: Mehlin Dean Matthews
