Reactant Parameters Control TRIZ Cases
- Nested Manifold Assembly for Compact Dual-Stack Fuel Cell Flow Routing
Overlapping branch and main channels route oxidant and coolant through dual-stack end plates while cutting manifold space and part count.
- Hydrogen Cartridge Power Generator With Controlled Fuel Cell Output
A reusable aluminum fuel cartridge reacts with fluid to generate hydrogen on demand, enabling quiet fuel-cell power without combustion emissions.
- Fuel Cell Jet Pump Bypass Duct for Hydrogen Entrainment
A venturi jet pump with first and bypass ducts boosts recycled hydrogen entrainment while avoiding added packaging space.
- Hydrogen Tank Leak Monitoring Using Temperature Difference Wake-Up
Temperature-difference wake-up monitoring detects hydrogen tank leaks and faults without continuous power draw, helping protect battery life.
- Fuel Cell Anode Valve Control for Nitrogen Purge Stability
Valve switching based on estimated anode nitrogen and target power helps purge nitrogen, maintain hydrogen concentration, and stabilize fuel cell output.
- Multilayer Hydrogen Tank Structure for Welded Stress Control
A welded thermoplastic polyamide and polyphthalamide layer stack cuts residual stress and microcracking while keeping hydrogen tanks light and gas-tight.
- Fuel Cell Vent Magnet Filter for Iron Particle Clogging
A movable magnet filter captures iron particles in the fuel cell vent and enables clogging control with simple accumulation notification.
- Fuel Cell Discharge Valve Diagnosis Using Pressure Difference
Pressure-based diagnosis checks whether a fuel cell integrated discharge valve is stuck closed, avoiding false shutdowns and unstable power.
- Fuel Cell Module Integration With Quick-Connect Maintenance Access
Quick-connect fuel cell modules and centralized control allow replacement without shutdown, reducing downtime and grid dependence.
- Hydrogen Fuel Cell Stack Control for Variable Fuel Purity
A controller switches recycle and single-pass hydrogen flow so fuel cells can run on 80-99.9% purity without costly purification.
- Fuel Cell Cooling Valve Switching for Lighter Heat Rejection
A multi-outlet coolant valve switches between recycle and exhaust modes to cut heat exchanger size, coolant volume, and aircraft drag.
