  • Patent number: 10411317
    Abstract: A metal-air battery includes an anode and a passivation layer formed on the anode. The passivation layer functions as electrolyte and cathode, so that no additional electrolyte or cathode is included. During discharge, metal cations derived from oxidation of the anode migrate across the passivation layer, and react with nucleophilic gas and electrons received from a gas diffusion layer. The metal-air battery, by virtue of having no added electrolyte or cathode, is compact and contains no volatile materials.

  • Patent number: 10355292
    Abstract: A method of controlling a fuel cell system includes supplying a fuel gas from a fuel-gas storage container to a fuel cell via a drive valve provided in a fuel-gas path. A first pressure is detected in the fuel-gas path between a first decompression mechanism and a second decompression mechanism. A second pressure is detected in the fuel-gas path between the second decompression mechanism and the drive valve. An on-off valve is opened. The on-off valve is provided in a bypass path. The first pressure and the second pressure are compared after the on-off valve has been opened. The fuel cell system is controlled to decrease electric power generated by the fuel cell or to stop generating electric power in the fuel cell when the first pressure is not substantially equal to the second pressure.

  • Patent number: 10329150
    Abstract: A system and method for determining the purity level of hydrogen gas fuel provided to an anode side of a fuel cell stack, and then modifying models and algorithms used by the system based on the purity level. The method includes determining whether predetermined criteria have been met that are necessary to obtain an accurate hydrogen gas fuel purity level, and if so, comparing a measured voltage or current of the fuel cell stack to a modeled voltage or current of the fuel cell stack. If the comparison between the measured voltage or current and the modeled voltage or current is greater than a predetermined threshold, then the method adapts a hydrogen gas concentration value to a lower purity level to be used by downstream models.
