Zinc-air technology exists for over one century. In a typical zinc-air fuel cell, there is at least a gas diffusion electrode (GDE), a zinc anode separated by electrolyte, and some form of mechanical separators. The GDE is a permeable membrane that allows atmospheric oxygen to pass through, after the oxygen has been converted to hydroxyl ions and water, the hydroxyl ions will travel through an electrolyte, and reaches the zinc anode . Here, it reacts with the zinc, and forms zinc oxide . This process creates an Electrical potential. When a set of zinc-air fuel cells are connected, the combined Electrical potential of these cells can be considerable, which can be used as a source of Electric power.
