I want also to build electrolysis based hydrogen generator or and water oxygenator/aerator. It's simple electrolysis device but requires special electrodes that are corrosion resistant or at least safe for human consumption. I seen that hydrogen bottles use platinum titanium electrodes. Platinum and gold have excellent resistance to corrosion but they are expensive. In this video I found good guide to electrolysis electrodes: https://www.youtube...h?v=Enf76lBNUIY
Graphite is cheap although also tends to break down, discolor water and has low conductivity (graphene?). Other alternative is MMO electrode which is harder to find and expensive. Also I have considered sacrificial non toxic metal electrodes for example iron or pure magnesium rod since these minerals are even beneficial.
There are cheap 16mm 99.99% magnesium rods on Ebay but since there are many scammers I might get instead magnesium rod with aluminum or other toxic metals. Any way to test purity?
Titanium without platinum might be also good option but I'm not sure, titanium dioxide is anyway used in food as white pigment.
Corrosion resistant anode would be better since I also have idea of building dual purpose device which could be used for aeration of roots in hydroponics like here:
