Fuel cells of tomorrow
In short, fuel cells (FCs) are electrochemical devices converting fuel's chemical energy to electricity at high yields. Theoretically, FCs can ensure a constant supply of electricity, if a constant supply of fuel is secured. The EU-funded project AMONCO investigated the use of biogas as the fuel component of FCs and any issues that might emerge from this combination. One of the key areas of focus of the project partners was the effect of specific components of biogases to the long-term integrity of FCs. It is known that the use of biogas in FCs is contingent upon the removal of specific trace gases, which can harm the FCs. The CSIC in Spain worked on identifying, at qualitative and quantitative levels, the influences of these gases on FC function and attributes. The final aim of the CSIC was to develop specific testing methods in order to evaluate contaminant tolerance. A variety of contaminant concentrations were examined at constant current density applying series of pulses at different intervals. CSIC is now in a position to offer a steady-state system for the study of different trace gases that can impair FC function. Energy companies seeking to discover the potential of alternative energy sources are likely to gain from the emerging scientific data and are invited to examine the possibility of long-term collaborations.
