This carbon paper, model HCP020P from Shanghai Heson, is a hydrophobic gas diffusion layer designed for use in fuel cells and related electrochemical research, including zinc battery and lithium-air battery studies. With a thickness of 0.2 mm and a porosity of 75%, it offers a balance between gas transport and structural support. Its waterproof treatment and low air resistance (<12 mmH₂O) facilitate effective water management in operating cells, while the resistivity of ≤16 mΩ·cm ensures adequate electronic conductivity. The material also demonstrates a bending radius greater than 10 cm, indicating acceptable mechanical flexibility for electrode assembly. Supplied in 21 × 20 cm sheets, this carbon paper is suitable for laboratory-scale fabrication and testing within experimental energy materials development.
