Benefits of technology

This new design improves the efficiency and effectiveness of solid oxide type (SOFCs), specifically ceramics that generate electric power from hydrocarbon fuels such as gasoline or diesel oil. These SOC's have several advantages over existing technologies like coal fired boilers for generating energy due to their high thermal stability compared to other methods. They also offer improved control capabilities during operation because they operate under specific conditions depending upon factors like temperature and humidity levels. Overall these improvements enhance the functionality and durability of SOFC systems while reducing manufacturing costs.

Problems solved by technology

The technical problem addressed in this patented text relating to traditional batteries used for generating electricity by converting chemicals into electrical current through electrochemistry involves having issues with size, weightiness, costs associated with producing these materials, and potential health hazards caused during production processes due to harmful substances released when they are produced.

Embodiment 1

[0051] Such as figure 1 As shown, a compact cylindrical ion-exchange membrane fuel cell 1 sequentially includes a compact pole-membrane integrated fuel chamber 2 , a cathode hydrophobic diffusion layer 3 and a cylindrical sealed collector cover 4 .

[0052] Such as figure 2 As shown, the compact pole-membrane integrated fuel cavity 2 includes a cylindrical fuel cavity 5, a honeycomb porous structure 6, and a fuel filling hole 7 at the top. Among them such as image 3 As shown, the honeycomb porous structure 6 further includes secondary channels 10 , an anode catalyst layer 11 and an ion exchange membrane 8 attached to the honeycomb porous structure 6 . The fuel filling hole 7 at the top is used for instant filling of liquid fuel to ensure quick start. The honeycomb porous structure 6 has a plurality of secondary channels 10 in the honeycomb holes. The more compact the honeycomb porous structure, the larger the catalytic active surface area, the smaller the mass transfer re...

Embodiment 2

[0058] In embodiment 2, the difference from embodiment 1 is that the cylindrical sealing header 4 is a complete cylindrical cylindrical structure made of memory alloy material, and there are enough circular air holes 12 to make the The air can fully contact the cathode. When assembling, first expand the radius of the memory alloy cylinder sealing collector 4 at low temperature, so that its diameter is slightly larger than the compact polar membrane integrated fuel chamber wrapped with the cathode hydrophobic diffusion layer 3 2. Then put the cylindrical sealed collecting cover 4 on the compact polar membrane integrated fuel chamber 2 wrapped with the cathode hydrophobic diffusion layer 3 at room temperature, and wait for its radius to return to the original radius to achieve interference Cooperate, provide enough external force to make the cathode hydrophobic diffusion layer 3 close to the compact polar membrane integrated fuel cavity 2, such as Figure 7 As shown, the fabrica...
