Fuel Cells TRIZ Cases
- Fuel Cell Bipolar Plate Groove Layout for Uniform Contact Pressure
A groove between the seal and flow regions absorbs frame connection buildup, equalizing contact pressure and preventing bypass and delamination.
- Fuel Cell Cooling Loop Using Pump Losses for Cold-Start Heating
By varying pump power losses, the cooling loop heats fuel cell components without extra heaters, cutting weight, space, and complexity.
- Fuel Cell Pressure Control for Membrane Leak Operation
Pressure balancing and inert gas control let a fuel cell keep running after a membrane leak while limiting heat and further damage.
- Fuel Cell-Combustor Assembly for SOFC Air Supply During Flameout
A fault-tolerant air supply keeps the SOFC operating through combustor flameout, preserving stack integrity and supporting engine relight.
- Fuel Cell Stack Current Extraction Structure for Sealing Integrity
A shortened section in the current extraction member absorbs cell stack displacement, reducing seal stress and improving housing reliability.
- Solvent-Free COF Synthesis for High Crystallinity at Scale
A solid-phase condensation route replaces solvothermal solvents and pressure vessels to produce crystalline COFs with scalable, greener processing.
- Fuel Cell Stack Drying via Anode Recirculation Reduction
Reducing anode hydrogen recirculation helps dry the cathode faster, limiting ice buildup and improving frozen-start reliability.
- Fuel Cell Water Separator Drain Control via Pressure-Based Empty Detection
Pressure changes upstream of the hydrogen metering valve reveal when the water container is empty, avoiding unreliable level sensors.
- Fuel Cell Cathode Humidification Using Exhaust Moisture Feedback
Pressure-drop and temperature feedback regulate cathode moisture using exhaust-water recovery to prevent membrane drying and flooding.
- Fuel Cell Serpentine Flow Channels With Blocking Ribs for Uniform Gas Flow
Blocking ribs create a serpentine-within-serpentine flow path that improves under-rib reactant distribution and fuel cell output.
- Bipolar Plate Laser Joining With Pulsed Polygon-Wheel Scanning
Pulsed laser scanning via a rotating polygon wheel joins fuel cell plates with lower heat input, reducing leaks and distortion.
- Fuel Cell Separator Projections for Vertical Air and Water Flow
Strategically placed channel projections create vertical air flow, raise gas residence time, and help discharge product water in fuel cell stacks.
- Fuel Cell Bipolar Plate Load Paths for Compression Alignment
Load-bearing extensions redirect compression forces from bipolar plate edges to central areas, preserving fuel cell stack alignment and plate shape.
- Bipolar Plate Composition for Conductivity Without High Molding Viscosity
A two-stage PVDF and conductive filler blend boosts bipolar plate conductivity and strength while avoiding high molding viscosity and post-treatment.
- Fuel Cell Stack Compression and 3D Flow Channels
Curved 3D plate channels and adjustable compression reduce pressure drop, water entrapment, and sealing limits in fuel cell stacks.
- Fuel Cell Reformer Housing for Replaceable Catalyst Maintenance
A split reformer housing with an interchangeable catalyst improves fuel cell maintenance, fastening stability, and service access.
- Fuel Cell Humidifier Layout for Active Water Evaporation
Atomized water, a humidifying grid, and active gas flow improve fuel cell gas humidification while keeping moisture distribution uniform.
- Graphite-Epoxy Fuel Cell Separator for Hot Flexural Fatigue
Controlled graphite particle size and height in an epoxy matrix improve fuel cell separator flexural strength and fatigue resistance at 70°C.
- Water Separator Empty Detection in Fuel Cell Anode Recirculation
Monitoring gas conveyor power during valve opening detects an empty water separator, cutting hydrogen loss and stabilizing anode pressure.
