Platinum black (Pt black) is a fine powder of platinum with good catalytic properties. The name

of platinum black is due to its black color.Platinum black is widely used as a thin film covering solid

platinum metal, forming platinum electrodes for applications in electrochemistry. The process of

covering platinum electrodes with such a layer of platinum black is called "platinization of platinum".

The platinized platinum has a true surface area much higher than the geometrical surface area of the

electrode and, therefore, exhibits catalytic action superior to that of shiny platinum.

Platinum black powder is used as a catalyst in proton exchange membrane fuel cells. In common

practice, the platinum black is either sprayed or hot pressed onto the membrane or gas diffusion layer.

A suspension of platinum black and carbon powder in ethanol-water solutions serves to optimize the

uniformity of the coating, electrical conductivity, and in the case of application to the membrane, to

prevent dehydration of the membrane during the application.
