In the context of chemical processes, such as chemical rockets, fuel refers to a reducing agent which can be chemically combined with an oxidizer to release energy. In other contexts, such as nuclear energy, it normally refers to the substance which is used as an energy source. In chemical propulsion, Fuel plus the oxidizer are propellants. In electric and most forms of nuclear propulsion, there are only propellants.
On Mars, fuels could be hydrogen, methane, carbon monoxide and metals, such as aluminium or iron. Oxygen is the most likely oxidizer. The abundance of water on Mars favors hydrogen and methane.
