Hydrogen Fuel Cells Disadvantage
On the Disadvantages of Hydrogen Fuel Cells
Although today's hydrogen fuel cells seem to have many advantages, they also have many drawbacks.
The first to bear the brunt is the difficulty in producing it. Although hydrogen is the most abundant element in the universe, on the earth, it mostly exists in the form of compounds. To obtain pure hydrogen, it is often necessary to electrolyze water and reform fossil fuels. Electrolyzing water requires a lot of electricity. If this power source comes from traditional thermal power, it will not only reduce carbon emissions, but also increase energy consumption. And reforming fossil fuels has not yet got rid of its dependence on fossil energy, and it also produces greenhouse gases, which is contrary to the hope of clean energy.
The second is the dilemma of storage. Hydrogen is a very light gas with active chemical properties. To store it effectively, it may require high-pressure compression or low-temperature liquefaction. High-pressure storage requires a special pressure-resistant container, which is expensive and poses a safety hazard. If the container is damaged, the leakage of hydrogen can easily cause explosion. Low-temperature liquefaction requires maintaining extremely low temperatures, energy consumption is huge, and the equipment is complex, which is not suitable for general conditions.
Furthermore, infrastructure is scarce. To make hydrogen fuel cell vehicles and other equipment run smoothly, the construction of hydrogen refueling stations is indispensable. However, today, the number of hydrogen refueling stations is scarce, far less common than that of gas stations. As a result, the use of hydrogen fuel cell vehicles is limited, and owners often worry about the difficulty of battery life and hydrogen refueling. It is like walking in a desert without water wells, which greatly hinders its promotion.
Again, the cost remains high. From the R & D and manufacturing of fuel cells to the construction and maintenance of supporting facilities, huge investment is required. The internal structure of fuel cells is precise, and key materials such as catalysts are expensive, resulting in high production prices. The high cost discourages consumers and makes it difficult to expand the market.
From this perspective, although hydrogen fuel cells have promising prospects, the current drawbacks still exist. To be widely used, many problems need to be overcome and breakthroughs need to be found to achieve perfection.
