Abstract
An illustrated example method of making a porous carbon composite includes mixing a carbon-based material, a binder and pore former particles to establish a mixture. The mixture is placed into a mold where it is subjected to pressure at an ambient temperature to form a compacted body. Subsequently, the compacted body is heated to a temperature that causes at least partial removal of the pore former particles to establish pores in place of at least some of the pore former particles.
