Organic chemistry, especially optical isomers make me most passionate. What am interesting about me? These molecules appear to show some behavior, but they are opposite in biology and stress the importance and impact of chemistry on other sciences. Since it incorporates physical science, why did I choose AS level physics and biology to delve into the topics covered by chemistry? Understanding the structure of these molecules, reaction mechanisms, and tests that prove the existence of molecules eventually is like a level of a blueprint, adding more information to the forecast.
Before proceeding, hydrogen fuel cells are considered to be the cornerstone of the theoretical hydrogen economy, so we need to understand what it is. Hydrogen fuel cells generate energy based on a simple reaction between hydrogen and oxygen, which emits a large amount of energy. The electricity generated by these fuel cells is almost pollution - most of the hydrogen and oxygen used to produce electricity will ultimately combine to form water, which is a harmless byproduct. Why are we preventing these hydrogen fuel cells from being used as the ultimate panacea for the current clean energy crisis? The answer is that it is impossible to get 100% pure hydrogen. This is because hydrogen atoms are known as smallest independent particles. Hydrogen fuel cells require pure hydrogen to produce the large amount of energy needed to produce enough electric power to run cars and buildings
Fuel cells generate electricity by combining hydrogen and oxygen. Hydrogen is supplied to the anode where the hydrogen molecules emit electrons which move towards the cathode of the fuel cell and generate current toward the motor. The hydrogen cation moves toward the cathode through the polymer electrolyte membrane, and the outside air is supplied to the cathode. They combine oxygen and electrons on the cathode catalyst to produce pure water and heat during the process - the only by-product
