Hydrogen fuel cells work by combining hydrogen and oxygen to produce electricity, water, and heat without combustion. Pure hydrogen gas is stored in high-pressure tanks and fed into the fuel cell. Within the fuel cell, a catalyst causes the hydrogen atoms to split into protons and electrons. The protons pass through a thin, solid polymer membrane t

Lithium hydroxide (LiOH) is an inorganic compound composed of lithium and hydroxide ions. It is a white crystalline solid that is highly soluble in water and soluble in ethanol. Chemically, it consists of lithium cations (Li+) and hydroxide anions (OH-). The chemical formula is LiOH and the molecular weight is 23.95 g/mol.   In its solid
