Hydrogen TRIZ Cases
- Two-Stage Fuel Reformer Using Copper Catalyst for Low-Cost SOFC Feed Gas
A thermally separated reformer lets a copper catalyst run below 350°C while downstream methanation supplies heat and cuts PGM cost.
- Liquid Desulfurizer Integration in Diesel Autothermal Reformers
Upstream liquid desulfurization uses combustor heat to avoid diesel cooling and reheating before SOFC reforming, cutting energy loss and complexity.
- Metal Hydride Hydrogen Storage With Thermal Coupling for Heat Reuse
A hydronic thermal loop couples metal hydride storage with electrolysis and fuel cell modules to reuse heat and improve efficiency.
- Magnesium Composite Hydrogen Storage Material With Catalytic Additives
Catalytic metals, carbon allotropes, and amorphous additives help magnesium store 6-7 wt% hydrogen with faster absorption and desorption.
- Magnesium Composite Material for Faster Hydrogen Uptake and Release
Casting, severe plastic deformation, and ball milling create a magnesium composite that improves hydrogen capacity, uptake, release, and working temperature.
- Hydrogen Reactor Startup Using a Catalytic Afterburner
Stored hydrogen is catalytically burned to self-heat the reactor at startup, avoiding external heaters while supporting fuel cell operation.
- Fuel Cell Reformer CO2 Capture With Hydrogen Recycle
Routing reformer output to CO2 capture and recycling separated hydrogen to the burner raises CO2 concentration and lowers capture cost.
- SOFC Fuel Cell Stack Heating with Integrated CPOX Shielding Gas
Internal CPOX shielding gas protects the SOFC stack during heat-up, avoiding a separate gas supply while reducing degradation risk.
- Closed-Loop CO2 Energy Storage With SOEC-SOFC Heat Recovery
Closed-loop CO2 recovery, storage, and heat reuse help an SOEC-SOFC energy storage system reduce conversion losses during power generation.
- Ammonia-Cracking Aircraft Power Plant for Waste Heat Recovery
Waste heat drives ammonia cracking to supply hydrogen for fuel cells and a thermal engine, improving aircraft power plant energy recovery.
- Multi-Chamber Metal Hydride Vessel for Low-Pressure Hydrogen
Segmented chambers, diaphragms, and an anvil flow channel store hydrogen in metal alloys at low pressure, improving volumetric density and safety.
- Direct Carbon Fuel Cell Integration for Low-CO2 Hydrogen Production
An integrated pyrolysis and direct carbon fuel cell route cuts hydrogen cost, generates power, and delivers a pure CO2 stream.
