Hydrogen Fuel Cell Disadvantages
On the Disadvantages of Hydrogen Fuel Cells
Hydrogen fuel cells have been noticed by everyone in recent years, but they also have various drawbacks, which cannot be ignored.
First, it is difficult to produce. Although hydrogen is widely used in the world, it is not easy to obtain high-purity hydrogen. The common water electrolysis method of hydrogen production consumes a lot of energy and costs money. And if the electricity used comes from fossil fuel power generation, it will not only lose the purpose of cleaning, but also increase carbon emissions, which is contrary to the original intention. For example, the reforming of natural gas to produce hydrogen, although the yield is acceptable, the process is also accompanied by greenhouse gases such as carbon dioxide, which is not a completely clean method.
Second, storage is difficult. The density of hydrogen is very small, and if you want to store enough hydrogen for use, it requires extremely high storage containers. High-pressure hydrogen storage requires special pressure-resistant containers, which are expensive and pose safety hazards. If you are not careful, you will be in danger of explosion. Although low-temperature liquid hydrogen storage can increase hydrogen storage capacity, it takes a lot of energy to maintain low temperatures, and liquid hydrogen is highly volatile, and storage losses are quite large.
Third, facility construction is difficult. In order to make hydrogen fuel cell vehicles run smoothly, the construction of hydrogen refueling stations is indispensable. However, the construction of hydrogen refueling stations is expensive, and professional equipment and technology are required. From site selection, planning to completion, it is time-consuming and laborious. And at present, the number of hydrogen refueling stations is scarce and scattered. For users, it is inconvenient to replenish and limit its wide application.
Fourth, the performance dilemma. The performance of hydrogen fuel cells is susceptible to environmental factors. At low temperatures, the reaction rate in the battery slows down, the output power decreases, and even cannot work normally. In high temperature and high humidity environments, battery components are prone to corrosion, which reduces their lifespan and affects their stability and reliability.
To sum up, although hydrogen fuel cells have prospects, their drawbacks are also obvious. To make them widely used, it is still necessary for researchers to make unremitting efforts to break through technical bottlenecks, reduce costs, improve performance, and solve the challenges of storage and facilities.
