HCP030N Carbon Paper (Hydrophilic)

This product is developed as a hydrophilic carbon paper for advanced electrochemical systems, including fuel cells, zinc batteries, and lithium–air batteries, where efficient gas diffusion and electrical conductivity are critical. With a thickness of 0.3 mm and a high porosity of 80%, the HCP030N offers low air resistance (<11 mmH₂O) and a resistivity of ≤12 mΩ·cm, supporting consistent reactant transport and minimal ohmic losses. Its non-waterproof structure makes it particularly suited for acid electrolyte environments, and the bending radius greater than 10 cm provides mechanical flexibility for custom electrode assembly. The material’s density of 0.78 g/cm³ and available dimensions of 21 × 20 cm further facilitate integration into laboratory-scale test cells or flow battery setups. This carbon paper is commonly employed as a gas diffusion layer or flexible electrode substrate, enabling reproducible performance in proton exchange membrane fuel cells (PEMFCs) and other aqueous electrolyte-based energy devices.
