Development and Characterization of Direct Formic Acid Fuel Cell for Potable Power Applications

Furthermore, Magnetic Resonance Imaging (MRI) is used to determine the spatial distributions of water and fuel in the membrane and GDL's of operating DFAFC. MRI images taken with a 14.7 T imaging system, show that the fuel distribution with the operating fuel cell is non-uniform. Generally, there is more fuel in the bottom of the cell, while the upper part of the flowfield is partially filled with CO2. Water distribution also shows non-uniformities. The areas of the GDL under the ribs in the flowfield are generally flooded, and there are other flooded spots that grow and shrink as performance changes.
