There would be a variety of fuels possible.  However, our internal combustion engines run predominantly on Hydrocarbons (Hydrogen + Carbon compounds).  Sulfur content is often considered as a contaminate, although it can burn.  If you have an alcohol or an ester, then you'd also have oxygen as part of the fuel.

A nuclear reactor would use Uranium, or a mix of other radioactive elements as fuel.

Theoretically, one could oxidize one of a number of different metals to derive energy.  For example, Aluminum will vigorously burn in certain conditions, but not in a manner that is easy to capture in our current internal combustion engines.  Batteries, however, tend to use the reactions of metals to store electricity.

Rocket engines must supply both the fuel and oxidizer.  Hydrogen + Oxygen is relatively light to carry, and can be stopped and restarted easily, but it is complex to contain the fuel.  Solid rocket fuels will use other oxidizers which are mixed in with the fuel so that both burn together.  Ammonium Perchlorate + Aluminum is one type of solid rocket fuel.

Magnesium, iron and aluminium get some use as a fuels as well.
Essentially, anything that forms a fairly stable oxide will do.

Do you remember asking a similar question and me answering that most elements will burn?
Do you understand that, since most elements will burn, they could be used as fuels?

What are you actually trying to find out?

I'll go along with BC on this question.

I suppose just about any element is a potential fuel, but those which react with another element vigorously would make the best fuels. Calcium, Sodium and Phosphorous for example, but since you would expend more energy purifying the element than you would get out of it, rather a pointless exercises.
