Abstract
The operating parameters have an important impact on the performance of a proton exchange membrane fuel cell (PEMFC). This paper investigates experimentally and numerically the cell temperature and relative humidity which have a significant influence on the PEMFC current density. These parameters are adjusted simultaneously and dynamically during operation. A 50 cm2 active area single-cell PEMFC with serpentine flow channel was studied. In order to confirm the experimental measurements, a mathematical model was established using the MATLpackage program and the results were compared. According to both experimental and mathematical model results, adjusting the operation parameters instantly according to the current value produced by the cell had a positive effect on the cell durability and performance.
期刊介绍：
The main aims of Thermal Science
to publish papers giving results of the fundamental and applied research in different, but closely connected fields:
fluid mechanics (mainly turbulent flows), heat transfer, mass transfer, combustion and chemical processes
in single, and specifically in multi-phase and multi-component flows
in high-temperature chemically reacting flows
processes present in thermal engineering, energy generating or consuming equipment, process and chemical engineering equipment and devices, ecological engineering,
The important characteristic of the journal is the orientation to the fundamental results of the investigations of different physical and chemical processes, always jointly present in real conditions, and their mutual influence. To publish papers written by experts from different fields: mechanical engineering, chemical engineering, fluid dynamics, thermodynamics and related fields. To inform international scientific community about the recent, and most prominent fundamental results achieved in the South-East European region, and particularly in Serbia, and - vice versa - to inform the scientific community from South-East European Region about recent fundamental and applied scientific achievements in developed countries, serving as a basis for technology development. To achieve international standards of the published papers, by the engagement of experts from different countries in the International Advisory board.
