This product, the HCP330N hydrophilic carbon cloth from Canrd, is developed for use as a gas diffusion layer or electrode substrate in fuel cell and electrochemical research applications. With a thickness of 0.32 mm and a soft hydrophilic treatment, it offers a balance of mechanical flexibility and wettability, which is critical for efficient water management in proton exchange membrane fuel cells. The longitudinal resistance is measured at 0.13×10⁻² ohms, providing adequate electrical conductivity within a lightweight structure of approximately 140–150 g/m² basis weight. Each sheet measures 32×16 cm, suitable for laboratory-scale cell assembly and material evaluation. This carbon cloth is designed to support consistent reactant transport and current collection, making it a practical choice for researchers developing and testing energy conversion devices.
