The Chromic acid cell is a type of primary cell which uses chromic acid as a depolarizer. The chromic acid is usually made by acidifying (with sulfuric acid) a solution of potassium dichromate. The old name for potassium dichromate is potassium bichromate and the cell is often called a Bichromate cell.[1] This type of cell is now only of historical interest.
