A jerrycan is typically used for having a robust fuel container which is originally made from pressed steel. It was designed in Germany to hold 20 liters of fuel.
The cathode in a fuel cell is typically made from a material like platinum, which serves as a catalyst for the oxygen reduction reaction. The anode is usually made from a material like nickel, which helps facilitate the oxidation of the fuel.
Attic stairs are typically made out of wood, including pine. Other common materials attic stairs can be made out of are metal, aluminum and fiberglass.
This is a very complicated question seeing as how there are many different colours and each colour in a firework is made by a very different chemical. Also their are many different ways to make each colour. For example blue can be made from potassium perchlorate, dechlorane, Copper II Oxide, red gum, and dextrin. But their is one thing in common for every firework formula. They have to include an oxidizer and a fuel. Take black powder for example, it consists of potassium nitrate (oxidizer), Sulfur (Fuel), and charcoal (Fuel) in a 75:15:10 mixture.

Rocket fuel is typically made by combining liquid oxygen (LOX) with a fuel source such as liquid hydrogen, kerosene, or a combination of various chemicals. These components are mixed in specific ratios to optimize performance and efficiency. The fuel is then stored in tanks on the rocket until it is ignited during the launch process.
For example plutonium is a nuclear fuel; also the isotope 233U.
Power Commanders are a common installation on Fuel Injected Motorcycles, for example any Yamaha r6 made after 2003.Power Commanders allow you to change out your fuel map ( i.e. change the fuel/air ratio) on your motorcycle for your needs.It is a way to even out your acceleration or increase horsepower. very common amongst racers.especially if you are going to upgrade your exhaust system and air filter you will need to adjust how much fuel is going to the throttle bodies or you will not gain the performance from your other additions.
