I am an Electrical engineering student trying a project in chemistry for credit. The project is to get pure Hydrogen out of urea using Electrolysis. Though the process of acquiring Hydrogen from urea is amazing but there isn't any information about the anode and cathode used in the process. So I do have the reaction taking place in the cell and it appears that the anode is Ni(OH)₂. What is the cathode of it?
I got most of my information here: https://www.ohio.edu/engineering/ceer/research/urea.cfm
So please let me know what are the cathode and anode of the cell.
If I have missed out some information feel free to ask.

Thanks in advance,
Conlock

Both electrodes could be nickel. But I am wondering that nitrogen is obtained. Normally urea decompose under alkaline conditions to ammonia.
