Abstract
A porous carbon-platinum electrocatalyst made from a carbon matrix-platinum composite, which has a carbon support and platinum is deposited into the pores of the carbon support. The platinum is at least 2 weight% of the carbon matrix-platinum composite. The carbon support has a nitrogen BET surface area of about 550 to 1800 m2/g; a packing density of at least 0.8 g/cc as determined at a compressive force of 500 kgf/cm2 on dry carbon powder; and an electrical conductivity of at least 10 S/cm at a compressive force of 500 kgf/cm2 on dry carbon powder. Also, an electrolyzer, comprising: the porous carbon-platinum electrocatalyst, wherein the electrolyzer has a Tafel slope of at most 40 mV / decade.
