Regenerative Fuel Cells TRIZ Cases
- Amine-Bromine Two-Electron Electrolyte for Higher-Density Flow Batteries
An ortho-substituted amine stabilizes bromine as N-bromo amine, enabling reversible two-electron transfer and higher flow battery energy density.
- Bipolar Plate Weld Pattern for Uniform Fuel Cell Current Density
An inhomogeneous weld pattern in a bipolar plate evens fuel cell current density, reducing MEA overload and extending service life.
- Laminated Donnan-Effect Generator With Multi-Ion Electrolyte Control
Using selective ion permeation between high-concentration electrolytes, this laminated Donnan generator raises power density and stability without external pumping.
- Slotted Felt Flow Structure for Redox Flow Cell Wetting
Slot-shaped openings in felt improve electrolyte flow, mixing, and electrode wetting while reducing shunt losses in redox flow cells.
- Polysulfide Flow Battery Electrolyte Using a Soluble Organic Catalyst
A soluble organic catalyst shifts polysulfide reduction to a chemical pathway, lowering overpotential and improving flow battery cycling.
- Flow Battery Bipolar Plate Fiber Coating for Slip-Free Carbon Felt
Laser-etched grooves and electrostatic carbon fiber flocking boost bipolar plate friction, prevent felt slip, and cut contact resistance.
- Flow Battery Rebalancing Cell for SOC and Osmotic Balance
An electrochemical rebalancing cell restores flow battery SOC while counteracting oxygen reactions and preserving osmotic balance.
- Redox Flow Battery Electrolyte Mixing for Capacity Rebalancing
A threshold-triggered cleansing cycle mixes positive and negative electrolytes to rebalance charge and limit redox flow battery capacity loss.
- Flow Battery Electrolyte Cooling for Integrated Thermal Storage
A flow battery uses its electrolyte for both cooling and energy storage, cutting separate thermal hardware size and weight.
- Redox Flow Battery Cleansing Cycle for Electrolyte Rebalancing
Mixing positive and negative electrolytes when capacity drops helps rebalance a redox flow battery and extend cycling without extra tanks.
- Sulfonic Acid Polymer Membranes With Low Hydrogen Permeability
A fluorinated sulfonic acid polymer balances high ion exchange capacity with low hydrogen permeability and a practical softening temperature.
- Double-Stack Iron Flow Battery Layout for Lower Weight Scaling
Vertical stacking with nesting detents raises iron flow battery capacity while cutting shared hardware, weight, cost, and footprint.
