網頁A galvanic cell based on the spontaneous reaction between copper and silver (I) is depicted in Figure 2. The cell is comprised of two half-cells, each containing the redox conjugate pair (“couple”) of a single reactant. The half-cell shown at the left contains the Cu (0)/Cu (II) couple in the form of a solid copper foil and an aqueous ... 網頁Electrochemistry. We encounter electrochemical cells in all facets of our everyday lives from the disposable AA batteries in our remote controls and the lithium-ion batteries in our iPhones to the nerve cells strewn throughout our bodies. There are two types of electrochemical cells: galvanic, also called Voltaic, and electrolytic.
