Abstract
Fuel cells are seen by many as key solutions, enabling clean efficient production of power from a range of primary energy sources. The laminar flow-based fuel cell (LFFC), which is actually membraneless, has recently been proposed to overcome some issues of PEFC such as manufacturing cost, material durability, fuel crossover and difficulty in water management. This study was aimed to improve the performance of LFFC and identify the factors that significantly affect the fuel cell performance. I-V characteristics and internal impedance were measured with a single cell setup by using methanol as fuel. The results showed that the cell performance was improved at higher operating temperatures and higher oxidant concentrations. The results also showed that activation, ohmic and concentration losses were correlated with the cell performance and that oxygen supply was the most important for further improvement of the cell performance.
