Collectors/Separators TRIZ Cases
- Crystalline-Coated Cell Stack Separator for Corrosion Resistance
Crystalline corrosion-resistant films on metal separators cut pinholes and cracks, improving acid resistance and stack operating life.
- Fuel Cell Bipolar Plate Channel Protrusions for Better Cooling
Channel protrusions create turbulent coolant flow in a fuel cell bipolar plate, improving heat transfer and preventing overheating damage.
- Bipolar Plate Channel Embossing for Wall Thickness Control
Non-parallel channel flanks guide in-plane material flow during embossing, creating wall thickness variation for better bipolar plate fluidics.
- Fuel Cell Stack Sealing Structure for Size Variation Absorption
Elastic seals at separator, clamping, and frame interfaces absorb size variation to prevent gas and refrigerant leaks in fuel cell stacks.
- Fuel Cell Separator Flow Layout for Uniform Reactant Distribution
Meandering and parallel channels balance pressure drop and reactant flow to prevent current density deterioration without enlarging the separator.
- Multi-Layer Fuel Cell Seal for Corrosion-Resistant Gas Sealing
Layered seal materials block reactant and coolant leakage while resisting corrosion in severe fuel cell stack environments.
- Bipolar Plate Flow Guide for Uniform Air and Water Distribution
A recessed-pocket flow guide evens air and water distribution in a PEM fuel cell bipolar plate, helping prevent water blockage and improve stack efficiency.
- Composite Polymer Electrolyte Membrane for Ion Conductor Retention
A porous support with crosslinking groups captures degraded ion conductor, preventing leakage and extending membrane durability.
- Fuel Cell Intermediate Layer With Cr2O3 for Low-Resistance Collection
Conductive particles in a Cr2O3 intermediate layer cut resistance at the metal support, improving corrosion resistance and fuel cell output.
- Separator Plate Weld Layout for Leak-Resistant Channel Crossings
A lowered web and offset weld end crater strengthen separator plate channel crossings, reducing cracks, leaks, and pressure-pulsation damage.
- Angled Conductive Rubber Voltage Tapping for Fuel Cell Edge Contacts
An angled conductive rubber contact improves fuel cell voltage tapping on narrow bipolar plate edges while resisting vibration and short circuits.
- Undulating Flow Field Plate for PEM Electrolyzer Compression
An undulating plate structure absorbs compressive loads in PEM electrolyzers while preserving reliable electrical contact without plastic deformation.
- Fuel Cell Separator Plate Layout for Freeze-Tolerant Low Pressure Loss
A perimeter-surrounding distribution region cuts pressure loss and keeps fuel cell gas flow reliable during freeze starts.
- Metal bipolar plate protective coating of fuel cell, and preparation method and application thereof
A Hf-HfO2-amorphous carbon multilayer coating helps fuel cell bipolar plates resist corrosion, avoid peeling, and keep contact resistance low.
- PEM Fuel Cell Bipolar Plate Layout for Low Pressure Drop Cooling
Z-shaped reactant channels and x-shaped coolant crossings cut pressure drop, improve flow uniformity, and shrink PEM fuel cell stacks.
- Wavy Rib Bipolar Plate for Fuel Cell Mass Transfer and Sealing
Wavy ribs and lofted side plates increase fluid disturbance and perpendicular convection while preserving sealing in fuel cell bipolar plates.
- Flow Field Plate Layout for Uniform Fuel Cell Media Distribution
Increasing cross-sections in stamped distribution fields improve edge-region gas supply and lower flow resistance in fuel cell plates.
