Abstract
A conductive microporous sheet material comprises primary carbon fibres having a cross-sectional dimension of at least 1 μm, secondary carbon fibres in the form of carbon nanofibres and a binding agent for binding said primary and secondary fibres. The material may be produced by a wet-laid non-woven (paper-making) process. The sheet material may be used as a gas diffusion layer for a fuel cell or an electrode material for a battery.
