Abstract
An electrochemical cell according to the present disclosure includes a casing provided with an inflow port and an outflow port, a bipolar membrane laminated body in which two or more bipolar membranes are laminated so as to be opposed, electrodes disposed so as to sandwich the bipolar membrane laminated body, and a first diffusion member disposed between the inflow port and the bipolar membrane laminated body, and provided with through holes communicating between the inflow port and the bipolar membrane laminated body. The first diffusion member is formed such that each of the through holes provided in a peripheral edge portion has a larger opening area than an opening area of the through holes provided in a central portion. This can uniformize a flow of water, so that water treatment can be efficiently executed.
