Counter-flow Membraneless Fuel Cell
A method for generating electrical current using a fuel cell includes flowing a first flow that includes a fuel and an electrolyte through a first channel. The fuel is oxidized at an anode to generate electrons for conduction to a load and oxidation products that remain in the first flow. The method includes flowing a second flow that includes an oxidizer and an electrolyte through a second channel that is open to the first channel. A cathode receives electrons from the load and the oxidation products, and the oxidizer is reduced to form reduction products and complete an electrochemical circuit. The plurality of exchange zones are positioned and the flows are oriented within their respective first and second channels such that the first and second flows contact one another intermittently at the exchange zones to enable transport of the reduction and oxidation products to the anode and cathode.
