Abstract
An electrochemical cell and a method of operating the same. In accordance with various embodiments, the cell includes an anode, one or more cathodes opposite the anode defining a pathway there between. Chemical reactions allow the electrolyte to flow through the defined pathway without requiring a pumping device.
Claims20
A metal-water electrochemical cell, the cell comprising:
- a metal anode within an enclosure;
- at least one cathode with a first surface that is adjacent to the anode and defines a pathway between the cathode and the anode;
- a porous or prismatic media within the enclosure;
- and
- an aqueous electrolyte that flows through the defined pathway without pumping, wherein:
- the electrolyte flows by at least one of molecular diffusion, a temperature gradient, or a phase gradient and
- the porous or prismatic media is configured to expand in a direction away from the anode and the at least one cathode.
