Comparative Studies of Polymer Electrolyte Membrane Fuel Cell Stacks and Single Cells

Abstract

We made a comparative investigation of a polymer electrolyte membrane fuel cell (PEMFC) with a single cell and a 30 cell stack. Various types of Nafion membranes, such as Nafion 102, 112, 115, and 117, and 105, were tested as electrolytes with the single cell at different temperatures. Nafion 112 gave us the optimal result. We evaluated the 30 cell stack at different temperatures and humidity levels. The potential current and power current curves for both the single cell and the stack were analyzed by computer simulation, during which the kinetic and mass transfer parameters were calculated. We also measured the performance of the stack and its water production during long term operation.
