Abstract

The invention relates to a high-efficiency electrolytic structure. Mainly, a tubular membrane comprises an outer conductive layer, an inner insulation layer disposed at an inner side of the outer conductive layer, a through hole formed at an inner side of the inner insulation layer, and a plurality of nanofiltration pores penetrate through the outer conductive layer and the inner insulation layer.

Description

According to reports, fuel cells using hydrogen as energy have long been regarded as having significant potential for generating stationary energy and being used in transportation. Its advantages include the ability to generate electrical energy more efficiently than internal combustion engines and other traditional energy devices. No pollutants are created during the basic process.

A fuel cell is a device that directly converts chemical energy into electrical energy. It does not require charging. As long as fuel and oxidant are continuously replenished, it can continue to operate and generate electricity. The fuel generates electrons after electrochemical reaction, and the electrons flow to another cell through electrodes and external circuits. An electrode reacts with an oxidant. After the oxidant accepts electrons, it reacts, and the electrolyte in the battery conducts ions, forming a circuit for battery operation. The fuel cell has the advantages of high energy conversion rate, stable voltage, and sustainable power supply.
