  • Patent number: 10916789
    Abstract: The invention relates to a system and method of operating alkaline exchange membrane fuel cells in a bipolar configuration. The system (400) may include a first fuel cell (300A) and a second fuel cell (300B) adjacent to the first fuel cell. Each of the first and second fuel cells may include: a cathode configured to generate hydroxide ions from water, oxygen and electrons, an anode configured to generate water and electrons from the hydroxide ions and hydrogen received from a hydrogen source, and an alkaline exchange membrane configured to transfer the hydroxide ions from the cathode to the anode, and to transfer water from a vicinity of the anode to a vicinity of the cathode. The first fuel cell (300A) and a second fuel cell (300B) are connected by a porous bipolar plate (430A) positioned inbetween.

  • Patent number: 10741849
    Abstract: In an AMFC, in the formation of a CCM, the anode catalyst layer is selectively cross-linked while the cathode catalyst layer is not cross-linked. This has been found to provide structural stabilization of the CCM without loss of initial power value for a CCM without cross-linking.

  • Patent number: 9368819
    Abstract: An air CO2 filtration assembly or system is provided that includes CO2 filters or traps designed and configured with a limited, but high capacity, volume to maximize filtration/absorption of CO2 from an air stream supplied to an alkaline fuel cell to thereby minimize the CO2 level in the air stream fed into the fuel cell cathode. The CO2 filters or traps include at least one thermally regenerative CO2 chemical filter or trap arranged in a tandem configuration with a strongly bonding CO2 chemical filter or trap. The combination of the two types of filters or traps sequentially filter/absorb CO2 from the air stream and reduce the level of CO2 in the air stream fed into the cathode. The air CO2 filtration assembly or system may be used in conjunction with electrochemical purging of the alkaline fuel cell that enables removal of CO2 from the fuel cell by anodic decomposition of accumulated carbonate ions in the fuel cell anode and release of CO2 through the anode exhaust stream.

    Abstract: A device to produce electricity by a chemical reaction without the addition of liquid electrolyte comprises an anode electrode, a polymer membrane electrolyte fabricated to conduct hydroxyl (OH—) ions, the membrane being in physical contact with the anode electrode on a first side of the membrane, and a cathode electrode in physical contact with a second side of the membrane. The anode electrode and cathode electrode contain catalysts, and the catalysts are constructed substantially entirely from non-precious metal catalysts. Water may be transferred to the cathode side of the membrane from an external source of water.
