Design of Hydrogen Fuel Cell: Methods to Higher Efficiency

Since climate change has become a visible and significant issue, all people sharing the planet earth should take action to solve the difficulties. Hydrogen power is the alternative energy to replace traditional energy such as coal, gasoline and so on. Hydrogen energy has a few features being unique and irreplaceable, great economic benefit, environmentally friendly, etc. The research paper has mainly focused on the development and current circumstance of a specific energy form, the hydrogen fuel cell. In the following paper, the working principle and five concrete typically fuel cells, including the solid oxide fuel cell, proton exchange membrane fuel cell, direct methanol fuel cell, phosphoric acid fuel cell, as well as alkaline fuel cell, are recommended with their working performances, advantages and disadvantages. Furtherly, suggestions have been given based on the further development of the materials for different parts of the hydrogen fuel cell. This paper aims to provide a practical route for further hydrogen fuel cell development and promote hydrogen economy and clean energy usage.
