Patent

CA 2569541

A gas diffusion substrate comprising a non-woven network of carbon fibres wherein the carbon fibres are graphitised but the non-woven network has not been subjected to a graphitisation process is disclosed. A mixture of graphitic particles and hydrophobic polymer is disposed within the network. The longest dimension of at least 90% of the graphitic particles is less than 100~m. Processes for manufacturing the gas diffusion substrates are also disclosed.

Substrat à diffusion gazeuse comprenant un réseau non tissé et de fibres de carbone graphitisées, le réseau non tissé n'ayant pas été soumis à un procédé de graphitisation. Un mélange de particules graphitiques et d'un polymère hydrophobe est placé dans le réseau. La dimension la plus longue d'au moins 90 % des particules graphitiques est inférieure à 100µm. Procédés de fabrication de ces substrats.
