Abstract
Fuel cells have been a source of green energy and are rapidly gaining applications in various fields. Laminar flow fuel cells are special type of fuel cell in which the oxidant and the fuel flow in parallel, mixed with the electrolyte, which substantially reduces losses due to mixing. This work focuses on the fabrication of paper based laminar flow fuel cells with a slit in between the two electrode areas to prevent further crossover. The capillary action of What man filter paper has been used which makes the cell self-pumping hence reducing the power requirements. Formic acid is used as fuel and potassium per magnate is used as oxidant. Concentration of the fuel has been varied and corresponding change in polarization curves, potentiometry, Impedance curves has been studied using Auto lab. The proposed cell can be used as a lateral flow in small diagnostic devices, which requires low power for their operation.
