- Cold hydrogen supply station and hydrogen-cooling device
See how a dual-coolant passage design with two heat exchangers cools hydrogen to -40°C with 13.
- Ejector, fuel cell system equipped with ejector and refrigeration cycle system equipped with ejector
See how upstream interior nozzle positioning prevents jet interference in dual-nozzle ejectors,
- Two-Stage Hydrogen Cooling Station for Precise Refueling Temperature Control
A two-stage coolant loop and feedback control cool hydrogen to refueling temperature with lower energy use and stable high-flow supply.
- Anode Recirculation Blower Cooling Using Dosed Process Water
A metered water feed from the separator reservoir passively cools the anode recirculation blower, cutting fuel cell system complexity and cost.
- Raised Bipolar Plate Feed Channels for Fuel Cell Stack Alignment
Raised feed channels contact the membrane frame to keep bipolar plates planar, improve cell alignment, and maintain uniform compression.
- High-Pressure Gas Tank Cap Threading to Prevent Radial Deformation
A threaded cap-to-protector joint shifts fastening force axially, preventing cap deformation while keeping the tank attachment secure.
- Detachable Pressure Vessel Nozzle for Rigidity and Weight Balance
A segmented detachable nozzle strengthens the boss neck while cutting vessel weight and adapting one pressure vessel design to different mounting methods.
- Gas Tank Detection Using a Pressure-Triggered Shutter Valve
A pressure-triggered shutter valve lets gas reach the detector at low pressure, improving remaining gas measurement when sensors lose accuracy.
- Anode Inlet Deflection for Fuel Cell Water Separation
A deflection means at the anode inlet separates recirculated product water before it reaches the fuel cell, helping prevent flooding and voltage loss.
- Fuel Cell Anode Pressure Sensing Under Sensor Abnormalities
When pressure sensors disagree, the control device estimates anode pressure and keeps fuel cell power generation running with the normal detector.
- Fuel Cell Shutdown Control Using Purge and Voltage Thresholds
Purge and voltage-based shutdown keeps a fuel cell in a safe state, limiting catalyst oxidation while avoiding added humidifier weight and space.
