Benzene is an important organic compound with the chemical formula C6H6, and its molecule consists of a ring of 6 carbon atoms, each with 1 hydrogen atom. Benzene is a sweet, flammable, colorless and transparent liquid with carcinogenic toxicity at room temperature, and has a strong aromatic odor. It is insoluble in water, easily soluble in organic solvents, and can also be used as an organic solvent itself. The ring system of benzene is called benzene ring, and the structure after removing one hydrogen atom from the benzene ring is called phenyl. Benzene is one of the most important basic organic chemical raw materials. Many important chemical intermediates can be derived from benzene through substitution reaction, addition reaction and benzene ring cleavage reaction.
Fuel Cells is a highly efficient, clean and renewable energy technology with many advantages such as low emissions, high efficiency, quiet operation and flexibility. They can use many different fuels, such as hydrogen, methanol, natural gas and biomass, making them highly adaptable and flexible. Fuel cell materials are essential components in the construction and operation of fuel cells, which are devices that convert chemical energy from fuels into electrical energy through an electrochemical process. There are several types of fuel cells, such as proton exchange membrane fuel cells (PEMFCs), solid oxide fuel cells (SOFCs), and molten carbonate fuel cells (MCFCs), each requiring different materials for their functioning.
