1 Introduction

Fuel cells are electrochemical devices where the energy of a chemical reaction is converted directly into electricity by combining hydrogen fuel with oxygen from air. Water and heat are the only by products if hydrogen is used as fuel source [1-3]. Therefore, fuel cells have attracted great attention in recent years as a promising replacement for traditional internal combustion engines due to their high power density and ultra-low emissions [4–6]. Among many kinds of fuel cells, the polymer electrolyte membrane (PEM) fuel cell has received much attention in the last two decades because fuel cells based on proton-exchange membranes have many attractive features, including high power density, rapid start-up, high efficiency, lightweight, compactness, which makes them a promising clean energy technology [6-10]. Thus, PEM fuel cells have been widely recognized as the most promising candidates for future power generating devices in the automotive, distributed power generation and portable electronic applications [6-12]. However, a number of fundamental problems must be overcome to improve their performance and to reduce their cost.
The primary aim of the study was to provide steady-state characteristics of the Nexa module (1.2 kW) for different stack temperatures and given load.


Scheme and view of the tested PEM fuel cell system are shown in Fig. 1 and Fig 2 respectively. The module tested is based on two fuel cell units 1.2 kW each produced by Ballard Power Systems Inc. and called Nexa – Fig. 3.
