This product is developed for use as a gas diffusion layer or electrode substrate in electrochemical energy devices such as fuel cells and electrolyzers. The Carbon Paper GDS210 from CeTech offers an open microporous structure that supports efficient mass transport, combined with good mechanical strength and high electrical conductivity. Available in a 20 cm by 20 cm sheet, it provides a balanced combination of structural integrity and conductive performance suitable for laboratory-scale research and prototyping. Its properties make it relevant for studies involving proton exchange membrane fuel cells and other advanced electrochemical systems where consistent current collection and reactant distribution are required.
