This paper reports the fabrication and characterization of a new concept of flow-through anode for membraneless laminar flow fuel cell (LFFC). To establish a reference case, a fuel cell with flow over and planar anode was fabricated as well. Experimental results indicated that maximum power density was improved from 17 m W/cm~2 in planar design to 23 m W/cm~2 using the flow-through design. The higher power density of flow-through design is an indicative of higher fuel utilization in the porous anode. Images of the flow obtained experimentally showed that mixing was reduced at the liquid-liquid interface in the channel with flow-through anode leading to increased fuel concentration over anode.
