What are the disadvantages of fuel cells?

What are the disadvantages of fuel cells?

Answer:

Fuel Type Single Currently, both hydrogen, gaseous hydrogen, hydrogen stored in hydrogen storage metal, and hydrogenated by carbohydrates after reforming are the only fuel for fuel cells. Hydrogen production, storage, storage, transportation and filling or reorganization, are more complex, the security requirements are high. But the fuel type of unity, you can establish a standardized, unified supply system.

Requiring a high-quality sealed fuel cell can produce a single battery voltage of about 1V, different types of fuel cells can produce a single battery voltage slightly different.

Usually a number of single cells according to the use of voltage and current requirements combined into a fuel cell engine group, in combination, the single cell electrode connection must be a strict seal, because the bad fuel cell, hydrogen will Leakage to the outside of the fuel cell, reducing the utilization of hydrogen and seriously affect the efficiency of the fuel cell engine, but also cause hydrogen combustion accident.

Due to the strict sealing requirements, making the fuel cell engine manufacturing process is very complex, and to use and maintain a lot of difficulties.

Need to be equipped with auxiliary battery system Fuel cell can continue to generate electricity, but can not charge and recover FCEV regenerative braking feedback energy. Often, the auxiliary battery is added to the FCEV to store the fueled fuel and the energy at the time of regenerative braking when the FCEV decelerates.
