This prototype is based on a hydrogen fuel cell (dry cell) which runs off a average car battery and produces enough gas to run a 5.5 hp AC generator which produces 220v, 2.2kw of electricity, so the theory is that you start the hydrogen fuel cell using an external battery once the fuel cell produces gas, the gas is pumped into the carburetor of the generator and the generator is the started charging the battery whilst producing a steady 220v.
Step 1: Building the Fuel Cell
There are many tutorials on building a fuel cell and are relatively easy to build with some know how.
Step 2: Bubblers and Piping
The purpose of a bubbler is to filter out and impurities out of the gas preventing dirty carburetors and sout build up in pipes, view diagram above
Step 3: The Generator
It is quite easy to add the generator but make sure to get one with an alternator installed ( otherwise you battery will not last very long and defeats to whole purpose ) to run it on gas simply make a hole in the air filter and remove all the foam inside.
you may need to adjust the timing of the engine to get it running smoothly.
Step 4: Operation and "making" Electricity
1. turn on your fuel cell
2. start you generator using the hydrogen
3. make electricity !
I hope you have fun and good luck !!!
