Fuel Cells TRIZ Cases
- Fuel Cell Stack Case Recess for Electrical Equipment
A fuel cell stack case features a recessed area to house an interruption control unit within the structural body.
- Fuel Cell Anode Gas Circulation and Nitrogen Management
Dynamic valve control balances nitrogen removal with hydrogen retention, preventing membrane dehydration.
- Non-Parallel Fuel Cell Gas Flow Channels for Water Management
Offset anode and cathode channels reduce flooding and pressure drop by orienting flow paths for gravitationally assisted water removal.
- Fuel Cell Compressor Control via Limitative Pressure
A fuel cell compressor control mechanism sets a limitative target pressure to stabilize rotation speed and suppress noise generation.
- Fuel Cell End Plate Through-Hole Curvature Design
Arcuate through-hole edges reduce injection molding stress while maintaining cross-sectional flow area.
- Fuel Cell Stack Activation Using Electrical Shorting
A fuel cell stack activation method uses electrical shorting between adjacent cells to decrease voltage.
- Displacement Absorption Tunnels for Circular Bead Buckling
Displacement absorption tunnels intersect circular beads to absorb compressive stress, preventing buckling and fluid leakage in plate assemblies.
- Fuel Cell Stack Water Drainage via Dummy Cells
Dummy cells at end portions drain condensed water, stabilizing voltage and protecting MEA catalysts from deterioration.
- Fuel Cell System Staggered Switching Control
A fuel cell system uses a control device to stagger switching times across multiple cells for continuous power generation.
- Fuel Cell Current Collector Edge Extension
Extended current collector edges increase edge area current density, lowering cathode potential to prevent membrane degradation.
- Solid Oxide Fuel Cell Gas Circuit Anode Pressure Control
A gas circuit design manages anode pressure in solid oxide fuel cells by positioning a conveying device upstream of a dividing device.
- Fuel Cell Stack Pressure Balancing via Diaphragm and Spring Strap
A fuel cell stack uses a spring strap and diaphragm to apply compressive force across the assembly.
- Fuel Cell Compressor Control via Delayed Valve Feedback
Delayed pressure regulation valve feedback suppresses cathode gas hunting while maintaining accurate flow rate control.
- Fuel Cell System with Integrated CO2 Capture and Internal Reforming
A fuel cell system integrates a separation assembly to extract carbon dioxide from anode exhaust streams.
- Fuel Cell Plate Ribbed Sealing Surface Design
Ribbed sealing surfaces on fuel cell plates integrate sealing functions to eliminate separate components and reduce device complexity.
- Fuel Cell System Overcurrent Detection and Fail-Safe Control
A fuel cell system monitors stack voltage and detects overcurrent to trigger immediate power generation stop.
- Fuel Cell Stack Mounting Structure with Movable End Plate
A fuel cell stack mounting structure uses a linear ball bush to guide the second end plate along the longitudinal axis.
- Polyurethane Foam Flame Retardancy via Phosphorous and Graphite
Phosphorous polyol and expandable graphite modify polyurethane foam composition to achieve V0 flame retardancy ratings, preventing rapid fire growth.
- Fuel Cell Control Device Humidity-Based Power Reduction
A fuel cell control device reduces power generation to dry the electrolyte membrane.
