摘要： The present application is directed to a gas-generating apparatus (10). Hydrogen is generated within the gas-generating apparatus and is transported to a fuel cell. The generation of hydrogen is regulated automatically by the selective exposure of a catalyst (48) to the fuel mixture depending on the pressure inside the reaction chamber (28) of the gas-generating apparatus. Catalyst sealing mechanisms (40, 42) are provided at least partially within the reaction chamber to regulate the hydrogen pressure and to minimize the fluctuations in pressure of the hydrogen received by the fuel cell.

摘要： A pair of fuel cells are configured as a hydrogen purity monitor. A first cell, acting as a reference cell, is configured to generate electrical current from the electrochemical reaction of hydrogen and oxidant and has a first fuel inlet configured to receive hydrogen from a first hydrogen source. A second fuel cell, acting as a test cell, is configured to generate electrical current from the electrochemical reaction of hydrogen and oxidant and has a second fuel inlet configured to receive hydrogen from a second hydrogen source. A control system is configured to apply an electrical load to each fuel cell and determine an electrical output of each fuel cell. The control system has a comparator for comparing the electrical outputs of the first and second fuel cells and a purity monitor output configured to give an indication of hydrogen purity based on an output of the comparator.

摘要： Methods of manufacturing a fuel cell array that include selectively removing portions of a coating layer from a composite layer. The composite layer includes a first surface and a second surface and a first coating is disposed over at least a portion of the first surface. A laser or mechanical tool is used to selectively remove portions of the first coating to form discontinuity regions at predetermined positions in the first coating.

摘要： Purge valves that are manually turned ON but are automatically or electrically turned OFF as the fuel cell production of electricity reaches a predetermined level, e.g., steady state or thereabout are disclosed. The purge valve may be opened at system start-up, or may be opened at system shut-down so that the purge valve is armed and the fuel cell system is purged at the next start-up. Also disclosed is an integrated fluidic interface module that contains various fluidic components including one of these purge valves. The integrated fluidic interface module can operate passively or without being actively controlled by a processor. Methods of operating a fuel cell system, wherein the fuel cell system is purged at system start-up, are also disclosed. The purging automatically stops when the anode plenum is fully purged and replaced with fuel.

摘要： A method of starting operation of a fuel cell system which includes at least a fuel cell stack the method includes opening an anode inlet valve to allow fuel to enter an anode volume of the fuel cell stack; then operating an air compressor in fluid communication with a cathode air inlet of the fuel cell stack to allow air to enter a cathode volume of the fuel cell stack monitoring the temperature of the cathode inlet and/or outlet operating a water injection system to inject water into the cathode volume once the temperature of fluid passing through the cathode inlet and/or outlet exceeds a preset level, wherein a current drawn from the fuel cell stack is limited to prevent a voltage measured across one or more cells in the fuel cell stack from falling below a first voltage threshold.
