Galvanic corrosion is a process that degrades metals electrochemically. These products then can be converted reversibly and electrochemically into LiZnN and metallic Zn. PCFCs can operate at high temperatures and electrochemically oxidize fossil fuels directly at the anode. The substance potential of a redox reaction is usually determined electrochemically current-free using reversible cells. Such networks can electrochemically oxidize organic contaminants, bacteria and viruses. Platinum also exhibits negative oxidation states at surfaces reduced electrochemically. Auxiliary electrodes are often fabricated from electrochemically inert materials such as gold, platinum, or carbon. The crystallization and recovery of aluminum hydride from electrochemically generated alane has been demonstrated. Triple phase boundaries are thus the electrochemically active sites within electrodes. The anion can be electrochemically oxidised to [BH]. This has been performed with alkali metals, electrochemically and with bases. Potentials in the kilovolt range can be realized without electrochemically degrading the hydrogel. Alternatively, the ligands can be electrochemically etched off. The highly valued ammonium perchlorate can be produced electrochemically. Large amounts of sodium hypochlorite are also produced electrochemically via an un-separated chloralkali process.
