    摘要: 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.
