 AlH4− - e− → AlH3 · nTHF + ½H2

2.3AlH4− + Al - 3e− → 4AlH3 · nTHF

In reaction 2, the aluminium anode is consumed, limiting the production of aluminium hydride for a given electrochemical cell.The crystallization and recovery of aluminum hydride from electrochemically generated alane has been demonstrated.
