The cycle begins with hydrogen produced from a PEC cell and nitrogen filtered from the air.
High pressure causes nitrogen and hydrogen gas to from into ammonia.
The ammonia then penetrates the porous MgCl2 salt and is absorbed to form the metal ammine.
The hydrogen can then be transported through the ammine to the fuel cell system.
