Hydrogen Fuel Systems Australia holds Australian Patent 2012261768. The patent was lodged in 2012 and modified 15 times during the testing period, covering a range of innovations that distinguish HFS systems from the ineffective "neutral plate" designs commonly sold online.
What the Patent Covers
The HFS patent covers the following improvements to electrolysis-based hydrogen fuel systems:
- Improved thermal stability of electrolytic cells
- Increased gas production mass flow rate
- Improved power supply efficiency and longevity
- Prevention of electro-stripping of electrodes
- More robust design for off-road conditions
- Reduced current load on the vehicle electrical system
- Safer design with flashback resistance
- MIG-welded electrodes to reduce cell resistance
- Laser-welded electrodes for further improved conductivity
- Laser-welded steel and aluminium enclosure boxes for greater robustness
- Specialist electrolyte development to protect plates and increase gas production
Why "neutral plate" units are different: Common "50-plate" neutral plate designs require ~100V to function (50 × 2V per cell). A 12V vehicle battery cannot provide this. These units convert electrical energy to heat and steam — not hydrogen. They cannot be patented because they cannot produce useful quantities of hydrogen gas at 12V.
Joint Venture with Kitech Hydrogen
HFS operates in joint venture with Kitech Hydrogen (Singapore) for the production of large-scale commercial systems. This partnership brings the patented HFS technology to international commercial markets including SE Asia and beyond.
