Latest Patents

One of Dean Paxton's latest patents is for a compliant current collector for fuel cell anode and cathode. This invention features an electrically-conductive mesh spacer that is integrated into the hydrogen and air gas flow spaces between each anode and cathode and its adjacent interconnect in a fuel cell stack. The mesh is constructed from metal strands and is designed in a predetermined three-dimensional pattern to ensure contact at multiple points on the surfaces of the electrode and the interconnect element. The mesh spacer is secured to the interconnect element at various locations, preserving its pattern during the assembly of a fuel cell stack. The height of the formed pattern exceeds the height of the gas flow space after assembly, allowing the mesh spacer to be slightly compressed during the process. This design ensures that the metal mesh remains compliant and resilient, maintaining continuous mechanical and electrical contact with the electrode under varying temperatures and pressures.

Another significant patent by Dean Paxton is for a modular fuel cell cassette for forming a solid-oxide fuel cell stack. This modular cassette consists of a metal separator plate and a metal cell-mounting plate that are joined at their edges to create a hollow structure. A fuel cell subassembly is attached to the mounting plate and extends through an opening in it. The plates are designed with openings that form chimney manifolds for the supply and exhaust of fuel gas to the anode and air to the cathode. A conductive interconnect element connects the fuel cell subassembly to the next cassette in the stack. The design includes spacer rings that separate the anode openings in the mounting plate and separator plate, ensuring that the cassette remains incompressible.
