An illustrative example fuel cell assembly includes a plurality of fuel cells arranged in a stack including a first end fuel cell near a first end of the stack and a second end fuel cell near a second end of the stack. Each of the fuel cells includes a matrix containing an electrolyte, an anode and a cathode on opposite sides of the matrix, and respective flow fields adjacent the anode and the cathode. An electrolyte supply associated with the anode flow field of the first end fuel cell includes a porous material containing electrolyte. An electrolyte collector associated with the cathode flow field of the second end fuel cell includes a porous material configured to collect electrolyte from at least the cathode of the second end fuel cell.

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.
