Palladium chloride powder is a chemical compound that can be found in powder form. It is a substance having the chemical formula PdCl2. The said formulation is an odourless, dark brown powder that dissolves readily in polar solvents like water. In the electroplating business, palladium chloride powder is employed to apply a thin palladium coating to various metal surfaces. Palladium-plated components are extremely corrosion-resistant and are used in jewellery, dental products, and electronics. It makes fuel cells and transforms chemical energy into electrical energy. This medicine serves as a catalyst in the electrodes of direct methanol fuel cells (DMFCs) and proton exchange membrane fuel cells (PEMFCs).
