Identification of the effects of trace compounds present in Biogas on different fuel C via single cell tests

It has been largely recognised that biomass will play a substantial role in the global energy balance. The use of biomass for power generation has a potential of solving, at least partially, the problem of non-renewable fossil fuel depletion.

Although a fuel cell produces electricity, a fuel cell power system requires the integration of many components beyond the fuel cell stack itself, for the fuel cell will produce only DC power and utilise only processed fuel.

Fuel conversion and alteration catalysts are normally susceptible to poisoning; thus the raw fuel cleaning process takes place upstream or within the fuel conversion process.

The main goal of our work is to determine and quantify the influence of these poisoning compounds in the Fuel Cells, in order to establish specific testing methods. To evaluate the tolerance of contaminants a novel automatic, dynamic and steady state methods was development.

The potential of fuel cell was measured at a constant current density applying a series of pulses with different concentrations of contaminants and different intervals of pulses. After poisoning the components of the fuel cell will be analysed using analytical techniques to try to assessed the real impact of it.
