6 FAQs about [Principle of portable hydrogen energy storage power supply]

Why is fuel storage important for portable power systems?

Fuel storage is critical for portable applications to provide energy densities above those of modern batteries. Start-ups, venture investors, and multinational conglomerates have invested millions of dollars and decades of research to bring these portable power systems to market, but much more effort is still needed.

Are hydrogen fuel cells a promising technology for portable applications?

Hydrogen fuel cells are clearly a promising technology. However, the great potential of these devices for portable applications still requires a strong effort in R&D activities.

How can a fuel cell maintain constant hydrogen pressure?

Constant hydrogen pressure can be achieved in an array of approaches. One method is to have a high-pressure hydrogen supply that is introduced to the fuel cell via a pressure-regulating valve, or a displacement approach in which the storage volume is reduced as the fuel is consumed in order to maintain constant gas pressure.

Do portable fuel cells improve specific power density?

This chapter compiles a survey of the R&D efforts considered in the most recent literature focused on the improvement of the specific power density of fuel cells for portable applications. A primary concern for portable fuel cells is the decrease in system volume and weight. This issue is usually tackled by reducing the system complexity.

Are fuel cells and hydrogen technology ready for commercialization?

Fuel cells and hydrogen technologies are still some distance away from full commercialization, but industry has already identified early markets to exploit some of their advantages, that is, high efficiency, longer runtime, low noise, low heat signature, and clean exhaust.

How much hydrogen does powerpaste release?

POWERPASTE releases hydrogen on contact with water. It has a hydrogen capacity of about 10 mass-% (i.e. 10 kg POWERPASTE → 1 kg hydrogen). This is a specific energy of 1.6 kWhel/kg and an energy density of 1.9 kWh/liter, or about 10 times the capacity of Li-Ion batteries.
