Abstract: A multiple physical finite elements to analyze software (COMSOL Multiphysics) is employed to investigate serpentine flow channels of a small proton exchange membrane fuel cell with power 0.5W. Distributions of the oxygen flow, the liquid water, and the electric current density in three different designed flow channels are simulated and compared. Results show that increasing the channel width is conducive to increase the oxygen flow and reduce the production of liquid water. It thus enhances the electric current density. However, it will reduce the oxygen flow, produce more liquid water, and depress the current density if the channel width is decreased.

Abstract: In modern life, factories and household electricity consume the largest amount of electric power, especially in summer. The continuous operation of air-conditioning system increases the heat in the environment and speeds up energy consumption as well. Therefore, in order to promote ecological balance, reduce carbon dioxide emission, and establish no pollution living environment, this study used green energy power generation technology, rainwater collection system, automatic light sensor-controlled curtain, infrared-controlled light, temperature sensor-controlled air-conditioning system, anti-theft system, and smoke-sensing device as effective devices for utilization of green energy. The rainfall collection system can increase the utilization of water resource. The curtain with light sensors, illumination system, and air-conditioning system can effectively save energy. The anti-theft system and smoke sensing device can both ensure the safety of living environment and achieve the objective of energy saving and carbon reduction, which can make the future living environment become more comfortable, energy-saving, and environmental-friendly. In addition, the devices above can also make contribution environmental protection of the earth and preserve a clean, beautiful, and sustainable environment for future generations.
