Motive System Fuel Cells TRIZ Cases
- Fuel Cell Control Architecture for Multi-Type Stack Adaptation
Environmental sensing and pre-charge control let one fuel cell platform regulate air and fuel circuits across different stack types and conditions.
- Fuel Cell Coolant Leak Detection Using Conductivity Fluctuations
Conductivity fluctuation monitoring enables rapid, reliable fuel cell coolant leak detection without relying on material-dependent level or temperature methods.
- PFSA Proton Exchange Membrane Additives for Low Hydrogen Cross-Over
Fluorocarbon-coated additives in PFSA membranes boost proton conductivity and strength while limiting hydrogen cross-over in fuel cells.
- Fuel Cell Air Temperature Control to Prevent Cathode Flooding
Regulating supercharged air temperature with coolant flow suppresses cathode condensation and flooding in low-temperature fuel cell operation.
- Fuel Cell Voltage Diagnosis for Reverse Voltage Compensation
Voltage-based diagnosis identifies reverse-voltage-prone fuel cells and adjusts hydrogen and air supply to limit degradation and fuel waste.
- Fuel Cell Stack Shutdown Drying Based on Slope Detection
Slope-based shutdown drying shortens fuel cell media-channel purge when gravity aids water removal, cutting energy use and icing risk.
- Fuel Cell Air Supply Reactivation During Shut-Down Conditioning
Immediate air supply speed-up during shut-down conditioning enables faster fuel cell restart while preserving proper cathode conditioning.
- Fuel Cell Wire Cooling Control for High-Current Heat Management
Wire-temperature feedback adjusts pump and fan speed to cool high-current fuel cell wiring while avoiding unnecessary pump energy use.
