Fuel Cells. ‌ Fuel cells are emerging as a strong alternative power source candidate. The technology has matured in recent years and has many benefits compared to generators, such as fuel efficiency, climate resistance, reliable start-up, and being very compact (e.g. fitting in a 19” rack). Their silent operation means there will be no indication that a power source is operating on the cell site, reducing the likelihood of theft. Having reached volume manufacturing and with prices falling, they will challenge conventional engine driven generators in terms of cost and reliability.

Fuel Cells. The principle of the fuel cell was invented in 1838, however the first commercial use of fuel cells came more than a century later in NASA space programs to generate power for satellites and space capsules. Since then, the improvement of the fuel cell began and nowadays they are used in many other applica- tions, e.g., for primary and backup power for commercial, industrial and residential buildings and in remote or inaccessible areas. The second most important application for fuel cells is as a power source for vehicles of all kinds. With fuel cells local emission-free power generation is possible. The comparison of a fuel cell with a conventional internal combustion engine shows that no mechanical stress on components takes place because no fuel is burned. However, the durability/lifetime of a fuel cell is much smaller compared to internal combustion engine. The sector calculates with 30,000 running hours for fuel cells and 200,000 hours for a combustion engine. This adds to further increase of the difference in the total cost of own- ership during the lifetime of a vessel and thus this is a big disadvantage for the fuel cell compared to the internal combustion engine. Another disadvantage is the dependency on the purity of the fuel which is less critical with H2 ICE for example.
