Hydrogen TRIZ Cases
- Integrated Hydrogen Steelmaking With Carbon Fuel Cell CO2 Capture
Pyrolysis, electrolysis, and a direct carbon fuel cell co-produce hydrogen, steel, and power while routing CO2 to sequestration.
- Fuel Cell Reforming With Thermally Decoupled Fuel Recirculation
Thermally decoupling reforming and hydrocarbon generation cuts heat loss, recycles residual fuel, and protects the anode at high utilization.
- Radial Fuel Cell Stack Layout Around a Tubular Reformer
A tubular reformer with outer cell stacks and an inner exhaust-gas combustor improves heat exchange and shrinks fuel cell system size.
- Integrated Digestion Fuel Cell Loop for High-Purity Syngas
Waste-to-fuel gas digestion is coupled with a fuel cell heat loop to avoid combustion dilution, protect catalysts, and raise hydrogen recovery.
- Aircraft Heat Sink Pod Using PCM Cooling and Hydrogen Power
Encapsulated PCM cooling and hydrogen-powered APU let an aircraft pod manage DEW heat without drawing on onboard coolant or power.
- Fixed-Bed Iron Oxide Reactor for Explosion-Proof Seasonal Storage
A fixed-bed FeOx reactor with a compensation element stores seasonal energy at ambient pressure while preventing hydrogen buildup and explosion risk.
- Catalytic Reformer Layout for Compact Fuel Cell Hydrogen Production
A multi-chamber reformer extends gas flow and heat transfer to improve methanol reforming completeness in a compact rack-mount fuel cell.
- Oxide Ion Conducting Membrane for Platinum-Free Hydrogen Production
A mixed-conducting oxide membrane produces high-purity hydrogen from steam in reducing conditions without platinum catalysts or fluid interconnects.
- Catalyst Heater Cutoff Control for Stable Combustion Light-Off
Heater shutdown is timed to fuel-generated heat, preventing catalyst cooling during fuel increase and preserving combustion efficiency.
- Fuel Cell Anode Channel Features for Nitrogen Purging
Cuts, cutouts, and grooves in the anode channel improve hydrogen diffusion and purge nitrogen, raising fuel cell voltage without pre-filtration.
- Fuel Cell Reforming Layout for Temperature Uniformity and Efficiency
Partial external reforming plus an internal catalyst layer improves hydrogen supply, limits temperature unevenness, and boosts fuel cell efficiency.
- Steam Reformer Gas Manifold Insulation for Uniform Jacket Temperature
Asymmetric insulation and a curved outer surface help a steam reformer gas manifold maintain uniform jacket temperature and limit thermal expansion.
- Metal Hydride Hydrogen Storage Predictive Tempering Control
A neural-network predictive controller pre-conditions tempering fluid to stabilize hydrogen flow while limiting temperature, pressure, and energy swings.
- Electrically Heated Reformer Tubes for Uniform Syngas Heating
Internal electric heating in reformer tubes evens catalyst temperature, cuts tube stress and methane slip, and lowers burner emissions.
- Digital Twin Ammonia Flow Control for Balanced Pipe Throughput
Real-time digital twin feedback balances ammonia flow across pipes to raise throughput, cut energy use, and improve plant reliability.
- Multi-Pressure Gas Header Layout to Minimize Compression Loss
Header valves route gas to pressure-matched outlets, avoiding excess compression and supplying multiple applications with lower energy loss.
- High-Temperature Tube Face Seals for Mismatched Thermal Expansion
A normal-force face seal keeps ceramic and metal tubes hermetically joined through thermal cycling without leakage or fatigue.
