Reactant Parameters Control TRIZ Cases
- Fuel Cell Anode Gas Pressure Control for Water Blockage
A controller adjusts anode gas supply pressure to discharge liquid water from fuel cell flow paths.
- Fuel Cell Hydrogen Supply Control via Stop Time Prediction
A hydrogen supply method measures fuel cell stop time to predict residual gas states and adjust anode pressure.
- Fuel Cell System Pressure-Based Fuel Discharge Estimation
A fuel cell control unit estimates discharged fuel gas volume by analyzing pressure fluctuations in the supply passage during intermittent injection cycles.
- Electrochemical Hydrogen Sensor for Real-Time Contaminant Detection
An electrochemical sensor array detects hydrogen contaminants in real-time using redox reactions between electrodes and an electrolyte.
- Fuel Cell Oxidant Flow Control via Pressure Valve
A pressure adjusting valve modulates oxidant gas supply to prevent membrane drying while keeping the rotational driving unit at minimum speed.
- Fuel Cell Gas Supply System Sensor Calibration
A buffer tank redirects hydrogen gas during sensor calibration, enabling rapid pressure equalization while eliminating fuel cell operation noise.
- Fuel Cell Shut-off Valve Anti-freeze Control
A fuel cell cathode control unit opens shut-off valves before anode scavenging to discharge residual water and prevent freezing.
- Infrared Hydrogen Charging Detection for FCEV Safety
Infrared transmission and reception units detect fuel door and nozzle states, preventing vehicle starting during high-pressure hydrogen charging.
- Electrochemical Device Corrosion Reduction via Tapered Branch Passages
Tapered branch passages in electrochemical devices promote self-reactions over corrosion, extending component lifespan.
- Adjustable Gas Foil Thrust Bearing Cap for Fuel Cell Blowers
Threaded bearing caps adjust gas foil thrust bearing preload without shims, eliminating assembly complexity and oil contamination in fuel cell blowers.
- Hydrogen Generator With Movable Barrier
A hydrogen generator employs a movable barrier to adjust volume ratios, resolving the trade-off between production capacity and storage needs.
- Fuel Cell Isolation Valve Safety Switch Mechanism
An isolating valve defaults to closed without power while a safety switch prevents accidental activation during maintenance, resolving reliability risks.
- Solid Oxide Fuel Cell Sealant for Gas Leakage Prevention
Glass sealant fills defects in solid electrolyte layers and interconnectors, preventing gas leakage while relaxing manufacturing precision requirements.
- Fuel Cell Cathode Freeze Strategy via Drip Rail Drainage
Cathode subsystem prevents water freezing using a drip rail with a protrusion and sump to manage condensed water near the backpressure valve.
