Fuel Cells TRIZ Cases
- Fuel Cell Assembly Ultrasonic Bonding for Faster GDL Fixation
Ultrasonic bonding fixes gas diffusion layers to reinforcements without external heating, cutting assembly time while preserving rigidity and integrity.
- Fuel Cell Tightening Structure for Uniform Stack Pressure
A two-plate tightening structure with a convex pressing part keeps fuel cell stack pressure uniform, lowering contact resistance and stress concentration.
- Fuel Cell Separator Tunnel Structure for Water Backflow Prevention
Arc-shaped tunnel bodies and a joint channel bypass the seal to discharge water smoothly, limiting backflow and pressure drop.
- Fuel Cell Stack Vent Tube Support for Air Bubble Discharge
Tapered end-unit supports stabilize a vent tube in the cooling discharge path, enabling accurate placement and reliable air bubble removal.
- Fuel Cell Stack Frame Structure for Manifold Insulation Alignment
A flexible frame with bent protrusions adapts to separator variation, improving manifold insulation and cell positioning during stack assembly.
- Bipolar Plate Web Height Layout for Uniform Coolant Distribution
Reduced web heights in bipolar plate distribution regions connect adjacent ducts, suppress cross currents, and prevent fuel cell hot spots.
- Fuel Cell Stack Pressure Control to Prevent Catalyst Layer Collapse
Adjusting stack clamping force after deterioration is detected helps prevent catalyst layer collapse and extend fuel cell life.
- Fuel Cell Bipolar Plate Alignment Without Flow Field Interference
Asymmetric corner aligning elements position and glue fuel cell plate halves accurately without disturbing the flow field or adding parts.
- Fuel Cell Stack Shutdown Voltage Control by Oxygen Concentration
Oxygen-based voltage ramp control during fuel cell shutdown limits stack deterioration while keeping battery charging power within bounds.
- Fuel Cell Stack Startup Current Control for Corrosion Prevention
Dynamic loading current control uses stack monolithic voltage thresholds to shorten fuel cell startup while preventing high-potential corrosion.
- Fuel Cell Airflow Compensation for Hydrogen Off-Gas Diffusion
Adjusts cathode air flow from hydrogen off-gas diffusion through the humidifier to protect oxygen concentration, output, and durability.
- Fuel Cell Stacking Height Control With Non-Contact Positioning
Non-contact height sensing and elevation control keep the fuel cell stacking surface aligned, cutting conveyance distance and energy use.
- Fuel Cell Resin Frame Venting for Unblocked Gas Supply
Ventilation portions in a resin frame keep manifold gas paths open, preserving fuel cell sealing and steady gas supply to the power unit.
- Fuel Cell Stacking Bar Holder for Precise Positioning and Removal
A dividable bar holder with detachable positioning bars improves fuel cell stacking accuracy, holding stability, and removal efficiency.
- Fuel Cell Stack Manifold Layout for Uniform Oxygen Distribution
Branching inlet and outlet channels distribute and discharge large oxygen flows evenly across multiple fuel cell stacks for higher power density.
