High Power Density Direct Formate Microfluidic Fuel Cells with the Different Catalyst-Free Oxidants.

ABSTRACT: As micropower devices, microfluidic fuel cells (MFCs) have gained much attention due to their simple configurations and high power densities. MFCs exploit the parallel laminar flowing of two electrolytes in a microchannel with a characteristic length from 1 to 1000 μm to separate the anolyte and catholyte, without the proton exchange membranes in the traditional fuel cells. These membrane-less configurations can avoid a series of technical problems related to the membranes. To achieve an MFC with high power density and low cost, we constructed the direct formate MFCs with two catalyst-free oxidants containing FeCl₃ and Na₂S₂O₈ solutions, respectively, and compared the performance of the two MFCs. Due to Na₂S₂O₈ be
