Pitch based graphite fabrics and needled punched felts for fuel cell gas diffusion layer substrates and high thermal conductivity reinforced composites

   
   

A pitch precursor yarn, which is stretch broken and formed into a fabric or felt which is heat treated into graphitic fiber media for fuel cell gas diffusion layer substrates and high thermal conductivity reinforced composites.

Um fio do precursor do passo, que seja estiramento quebrado e dado forma em uma tela ou sentido qual é calor tratado em meios graphitic da fibra para carcaças da camada da difusão do gás da célula combustível e compostos reforçados elevados do conductivity térmico.
