Electrochemical cell including channel-type flow electrode unit structure

The present invention relates to an electrochemical cell including a channel-type flow electrode unit. A channel-type flow electrode unit structure including at least two channel-type flow electrode units according to the present invention has an electrode capacity expanded to be suitable for use in large-scale plants for electricity generation, energy storage, desalting and the like, includes a reduced number of components, which bring about a significant reduction in production cost and installation space, and finds applications in capacitive flow-electrode devices and/or redox flow-electrode devices and even in any device that uses the migration of ions or protons in electricity generation, energy storage, or desalting.
