Fuel Cells Grouping TRIZ Cases
- Fuel Cell Stack Datum Nesting for Inter-Cell Sliding Resistance
Nested datum structures on bipolar plates prevent inter-cell sliding under high acceleration loads up to 160 g without adding weight or complexity.
- Battery Cell Stack Corrosion Resistance via Cushion Member
A battery cell stack uses a deformable cushion member between current collector and end bipolar plates to maintain electrical conductivity.
- Fuel Cell Monitor Cell Pressure Loss Design
A fuel cell monitor cell uses controlled hydrogen pressure loss to detect system abnormalities.
- Clad Copper Wire for Fuel Cell Current Collectors
A clad copper wire with Crofer cladding conducts current in fuel cell current collectors while resisting oxidizing and reducing environments.
- Air Cooled Fuel Cell Electronics Module With Split Air Zones
Segmented housing with a heat exchanger separates stagnant and ventilated zones, reducing corrosion risks while maintaining cooling efficiency.
- Fuel Cell Stack Electrolyte Flow Channel Design
Segmented open electrolyte flow channels with weirs minimize ionic leakage currents and ensure uniform pressure distribution in fuel cell stacks.
- Bipolar Plate Ribs for Fuel Cell Fluid Sealing
A bipolar plate uses structural ribs to form fluid communication channels between peripheral cut-outs and active zones.
- Bonded Polyimide Fuel Cell Package Integrating Heaters and Manifolds
A bonded polyimide fuel cell package integrates resistive heaters and fluid manifolds into a single layered structure.
- Fuel Cell Gas-Flow Passage Reinforcement for Durability
Segmented gas-flow passages with internal reinforcing portions prevent deformation and leakage while minimizing pressure loss in fuel cell stacks.
- Fuel Cell Cathode Stoichiometry Control for Humidity Stability
Dynamic cathode stoichiometry control minimizes relative humidity excursions during stack load transients, preventing membrane drying or water accumulation.
- Resin Fluid Manifold with Ribs for Fuel Cell Stack Weight Reduction
Ribs on a resin fluid manifold member reduce weight while maintaining structural integrity and improving heat dissipation efficiency.
- Bipolar Plate Inclined Grooves Corner Flow
Inclined grooves on bipolar plates direct electrolyte flow through independent introduction and discharge paths, resolving insufficient circulation at corners.
