System requirement

- The system shall be able to produce hydrogen and oxygen, separately.

Physical requirements 

- The electrodes shall be able to withstand the electrolysis temperature.

- The pipe system shall be able to withstand a temperature up to 100°C.

- The valves shall be able to resist the temperature and the pressure.

- The condensers shall be able to condense the vapor leaving the cell, with water.

Chemical requirements 

- The electrodes shall be able to withstand the corrosion with KOH.

- The membrane shall be able to allows the ions to pass through so that electrolysis takes place when the current is connected.

- The membrane shall be able to insulate the two half-cells, chemically. 

- The membrane shall be made of Nafion.

- The pipe system used shall be able to withstand the corrosion with KOH.

- The valves shall be able to withstand the corrosion with KOH.

- The metal of condenser used shall be able to withstand the corrosion with KOH.

Mechanical requirements 

- The electrodes shall be thick enough to withstand the pressing (the pressing of the screw rods).

- The electrodes shall be thick enough to press the gaskets so that no gas can exit.

- The gaskets shall be able to prevent the leakage of gases and liquids from the cells.

- The gaskets shall be made of thermal caoutchouc.

- The pipes connections shall be able to resist the gas pressure without let gas exit through.

- The pressure of the pump shall be sufficient to fill the cells and not too high for the pipes system.

- The valves shall be able to close completely.

- The valves shall be able to open or close with independent pressure.

Electrical requirements 

- For power supply, DC the current that pass through one cell shall be about 140 A DC and we have to test how much voltage shall be needed to make that.

- The power supply shall be able to let the electrolyze generates enough hydrogen so that we can burn it.

- The valves shall be able to be controlled from the GUI.

Safety requirement

- The hydrogen burner shall be able to burn the produced hydrogen gas to avoid the risk of its explosion.
