  • Advanced selectively gas permeable anode flow field design for efficient removal of carbon dioxide in a fuel cell
    Patent number: 11728493
    Abstract: An improved or advanced electrically conductive selectively gas permeable anode flow field (SGPFF) design, allowing for efficient removal of CO2 perpendicular to the active area near the location where it is formed in the catalyst layer. The anode plate design includes two mating flow fields (an anode gaseous flow field, and an anode liquid flow field) separated by a semi-permeable separator. The separator comprises a hydrophobic semi-permeable separator for CO2 diffusive gas transport from the liquid side (with acid, water, and CO2) to the gaseous side (allowing for CO2 removal to the atmosphere).
    Type: Grant
