... single fuel cell, have to be performed to confirm the good long-term performance of the CNTs as a support for fuel cell catalysts 3.3 Carbon nanohorns and nanocoils Carbon nanohorns and carbon ... Introduction Low- temperature fuel cells, with either hydrogen (phosphoric acid fuel cell, PAFC, and polymer electrolyte membrane fuel cell, PEMFC), methanol (direct methanol fuel cell, DMFC) or ... and 1000 rpm Carbon nanocoils were grown at 700 8C for 30 using C2H4 gas Few works have been performed on catalysts supported on CNHs or CNCs for use in low- temperature fuel cells For this reason,...
