Summary Fuel cells generate electricity (DC) from hydrogen through direct electrochemical conversion. Hydrogen is a fuel that can be produced from renewable energy sources and is considered to be a fuel of the future. Fuel cells are very versatile and have many possible applications from cellular phones to automobiles. Fuel cells with polymer membrane (PEM) which work at reatively low temperatures (from room temperature to 80°C) are most commonly used. Particularly interesting are passive fuel cells with oxygen supply from air by natural convection, because that way many parts of otherwise complex system (blower, humidifiers, heat exchangers ) may be eliminated. Because of limiting parameters such as oxygen supply, product water removal, and product heat removal, their current density is typically limited, so these fuel cells are in general suitable only for relatively low power applications (a few Watts). The objectives of the proposed research project is to identify and quantify the limiting processes through a combination of numerical modeling of processes and structures and experimental diagnostics, and then increase achievable current densities through improved design, appropriate selection of of materials and structures and optimized working parameters. The goal of this project is to significantly improve performance of passive fuel cells and because of that allow their wider applications )small portable generators, chargers, and even for small vehicles, scooters). The findings from the project will be published in the leading technical and scientific journals and presented at international conferences dedicated to fuel cells and/or heat and mass transfer. Knowledge generated in this project could find direct application in larger fuel cells even with forced air supply, with even more versatile applications.
