- Bipolar Plate Diaphragm Control for Fuel Cell Flow Balancing
An insertable diaphragm in a tapered bipolar plate media guide adjusts reactant flow and humidity for faster fuel cell power changes.
- Pressurized Solid Oxide Cell Stack Sealing Without External Vessels
Integrated seals and interconnects let a solid oxide cell stack run above atmospheric pressure without an external pressure vessel.
- Fuel Cell Separator Channels for Uniform Gas Distribution
Branched separator channels and a cover member spread fuel and air evenly across the stack, reducing hotspots and concentration gradients.
- Fuel Cell Vaporizer Cartridge for Recharge-Free Heating
A low-temperature solid oxide fuel cell powers vaporizer heating without recharging, cutting material use and enabling longer portable operation.
- Fuel Cell Separator Rib Protrusions to Prevent GDL Sinking
Rib protrusions pre-compress the GDL and frame member to stop groove sinking, cut gas-flow resistance, and reduce pressure loss.
- Fuel Cell Manifold Hole Structure to Prevent Frozen Gas Passage Blockage
A separator wall protrudes into the manifold hole to drain water droplets, preventing frozen gas passage blockage and improving fuel cell startability.
- Fuel Cell Separator Rib Recesses to Prevent GDL Sinking
Rib recesses and inclined inner side surfaces keep the GDL taut, stabilize gas flow, and reduce pressure loss in fuel cells.
- Fuel Cell Stack Sealing Ribs to Limit Compression Set
Ribs placed around the inter-cell seal control 20-70% compression, reducing permanent deformation and preserving fuel cell stack sealing.
- Fuel Cell Composite Member Surface Roughness for Chromium and Leak Control
Different roughness on exposed and covered surfaces improves coating adhesion, reducing chromium release and fuel gas leakage in fuel cell stacks.
- Dual-Pore Gas Diffusion Layer for Fuel Cell Mass Transport
A dual-pore microporous layer improves fuel cell gas and water transport while preserving catalyst contact and protection.
- Layered Conductive Member for Durable Fuel Cell Bonding
Open-pore oxide layers with smaller particles improve interlayer bonding, reduce peeling, and extend fuel cell stack durability.
- Fuel Cell Subgasket Edge With Through-Plane Proton Conduction
A transitional proton-conductive edge layer redirects PEM overlap current through-plane, reducing cerium migration while preserving sealing and active area.
- Metal-Supported Polymer Electrolyte Membrane for Radical Resistance
A metal porous support filled with ion conductor reinforces the membrane and scavenges radicals to sustain fuel cell operation in harsh heat and low humidity.
- SOFC Hot Box Layout for Thermal Uniformity and Lower Heat Loss
Cathode flue gas fills the hot box cavity and burner opening to improve thermal uniformity, cut heat loss, and shrink SOFC package volume.
