The given statement is true.
Polymer electrolyte membrane (PEM) fuel cells, that are also called as Proton-exchange membrane fuel cells, are a kind of fuel cells which are used or stationary fuel-cell applications, for transport applications, and for other portable fuel-cell applications.
The material that is used for building the current collector in the PEM cells is expected to have a very good electronic conductivity, apart from being a strong electro-chemical, and having mechanical stability, be a light weight material, and have low cost. This is important so as to reduce the weight of the fuel cell stack.
The most common materials that are used for making the current collectors in PEM fuel cells include copper, aluminum, titanium, and stainless steel.
