HCP030P Carbon Paper (Hydrophobic)

This product is developed for use as a flexible electrode substrate in advanced electrochemical systems, including fuel cells, zinc‑battery and lithium‑air battery research. The HCP030P hydrophobic graphite paper features a 0.3 mm thickness with a density of 0.78 g/cm³ and a porosity of 75%, providing a balance of mechanical flexibility and structural integrity. Its waterproof treatment makes it particularly suitable for acidic electrolyte environments, where moisture management is critical. With a low electrical resistivity of ≤18 mΩ·cm² and moderate air resistance (<12 mmH₂O), it supports efficient charge transport and gas diffusion. The material can be bent to a radius greater than 10 cm without damage, enabling integration into compact or flexible cell configurations. Common applications include gas diffusion layers, current collectors, and electrode backings where both conductivity and liquid repellency are required.
