Platinum nanoparticles, which are used as catalysts in Proton Exchange Membrane Fuel Cells (PEMFC), tend to degrade after long-term operation. We discriminate the following mechanisms of the degradation: poisoning, migration and coalescence, dissolution, and electrochemical Ostwald ripening. There are two ways to tackle this problem. The first option involves formulation of durable catalyst, wh...

This paper presents the development of the electrical and mathematical models which is able to simulate the static and dynamic phenomena of proton exchange membrane fuel cell (PEMFC). The models were validated against the current distribution data experimentally measured earlier. A parallel computational methodology was employed to substantially reduce the computational time and to make large-s...

In order to optimise the performance of Proton Exchange Membrane Fuel Cells (PEMFCs) and maximise their life cycle, water content has be properly controlled. This paper presents a model-based method determine effect load on PEMFC in PEMFCs using Acoustic Emission (AE) measurements. The developed model was implemented COMSOL verified single proton exchange membrane fuel cell (FC) operated under ...

The possibility of implementing fuel cell technology in Unmanned Aerial Vehicle (UAV) propulsion systems is considered. Potential advantages of the Proton Exchange Membrane or Polymer Electrolyte Membrane (PEMFC) and Direct Methanol Fuel Cells (DMFC), their fuels (hydrogen and methanol), and their storage systems are revised from technical and environmental standpoints. Some operating commercia...

Fuel cells, providing an advanced alternative energy source, are devices that can convert chemical into electrical energy. Modeling of a fuel cell provides improvements to the design cells as well cheaper, better and more efficient cells. Three basic voltage losses occur in cell: activation polarization, ohmic polarization concentration polarization. In this study, simulation PEM (proton exchan...
