What are the different types of fuel cells?

What are the different types of fuel cells?

Types of Fuel Cells

  • Polymer electrolyte membrane fuel cells.
  • Direct methanol fuel cells.
  • Alkaline fuel cells.
  • Phosphoric acid fuel cells.
  • Molten carbonate fuel cells.
  • Solid oxide fuel cells.
  • Reversible fuel cells.

What are the five types of fuel cells?

1 Development task of fuel cells The fuel cell is classified into some kinds after the electrolyte used as follows: PAFC (phosphoric acid fuel cells), PEFC (polymer electrolyte fuel cells), MCFC (molten carbonate fuel cells) and SOFCs. In PAFC and PEFC, proton (H+) moves in the electrolyte.

Which fuel cell is best?

Alkaline Fuel Cells Operating at 60-70ºC (140-158ºF), AFCs are among the most efficient type of fuel cells, reaching up to 60% efficiency and up to 87% combined heat and power. Both the US and Russian/Soviet spaceships used alkaline fuel cells to produce electricity and drinking water for astronauts.

What is the difference between Pemfc and SOFC?

PEMFC has a lower capex compared to SOFC but SOFC can utilize natural gas which is cheaper than hydrogen. PEMFC has the highest power to volume ratio, however it runs on hydrogen which has low volumetric density compared to tradition marine fuels.

What are the 6 types of fuel cells?

Fuel cells are generally characterized by the type of electrolyte material. These cells are mainly consisted of: Alkaline Fuel Cell (AFC), Molten Carbonate Fuel Cell (MCFC), Phosphoric Acid Fuel Cell (PAFC), Proton Exchange Membrane Fuel Cell (PEMFC), Solid Oxide Fuel Cell (SOFC), and Biofuel Cell [9,10].

Who invented the fuel cell?

William Robert Grove
Fuel cell/Inventors
First invented in 1839 by Welsh scientist William Robert Grove, the fuel cell wasn’t commercially used until the 1960s. As part of Project Gemini — which took part from 1962-1966 — NASA used fuel cells to generate power for probes, satellites and space capsules.

What are the advantages and disadvantages of fuel cells?

Benefits and Disadvantages

  • High Efficiency- when utilizing co-generation, fuel cells can attain over 80% energy efficiency.
  • Good reliability- quality of power provided does not degrade over time.
  • Noise- offers a much more silent and smooth alternative to conventional energy production.

Are fuel cells a better technology?

Fuel cells have strong benefits over conventional combustion-based technologies currently used in many power plants and cars. Hydrogen-powered fuel cells are also far more energy efficient than traditional combustion technologies.

How are fuel classified?

Generally, fuels can be classified into two factors: Based on their physical state, i.e. based on the state they are available in nature. -Solid fuel: These are found in their solid state at room temperature, for example, coal, wood, etc. Solid fuels are easy to transport and store and also have a low production cost.

Which is a comparative study of fuel cell technology?

The current paper includes a comparative study of basic design, working principle, applications, advantages and disadvantages of various technologies available for fuel cells. In addition, techno-economic features of hydrogen fuel cell vehicles (FCV) and internal combustion engine vehicles (ICEV) are compared.

What makes a fuel cell different from other fuel cells?

It happens between the oxygen and hydrogen to form the water. There are a range of designs available for fuel cells; however, they all operate with the same basic principles. The main difference in various fuel cell designs is the chemical characteristics of the electrolyte [3].

What kind of applications can fuel cells be used for?

In addition, applications with essential secure electrical energy requirement such as uninterruptible power supplies (UPS), power generation stations and distributed systems can employ fuel cells as their source of energy.

Which is better hydrogen fuel cell or internal combustion engine?

In addition, techno-economic features of hydrogen fuel cell vehicles (FCV) and internal combustion engine vehicles (ICEV) are compared. The results indicate that fuel cell systems have simple design, high reliability, noiseless operation, high efficiency and less environmental impact.
