Abstract: An electrolytic cell includes a cation exchange membrane, a cathode compartment, and an anode compartment. The cathode compartment includes a gas diffusion electrode and a flow channel element, in which the flow channel element is between the cation exchange membrane and the gas diffusion electrode, and has a plurality of flow channels arranged in parallel with each other. The anode compartment includes an anode mesh, in which the cation exchange membrane is between the anode mesh and the flow channel element. A distance between the anode mesh and the gas diffusion electrode is substantially equal to the sum of a first thickness of the cation exchange membrane and a second thickness of the flow channel element. The novel electrolytic cell can combine with a chloralkali electrolytic cell to deal with gaseous CO2 and produce products, e.g., synthesis gas, for other purposes.

Abstract: A method for controlling an electronic device by handwriting includes the steps: (a) receiving a handwritten pattern for recognition; (b) analyzing the handwritten pattern to divide the handwritten pattern into a primary feature and a secondary feature; (c) searching the storage device for a second predetermined pattern having the primary feature; and (d) comparing the second predetermined pattern with respect to the secondary feature in order to select a third predetermined pattern, in which, the secondary feature matches the handwritten pattern; (e) executing an operation function of the electronic device represented by the third predetermined pattern.
