Fuel Cell Systems Laboratory - TU Delft (Section Energy Technology)
•Electrochemistry (anodes)
•biofuels for SOFCs
•Influence of contaminants on SOFCs
•SOFC integration in power plants
The group has CFD tools for fuel cell modeling such as Fluent and COMSOL. Thermodynamic system studies are carried out using the in-house developed software Cycle Tempo. Several other software tools are used for a variety of applications. Thermodynamic evaluations and CFD calculations are often carried out in combination with experimental investigations. The group has access to several workstations for computational studies.
SOFC Cell test Stations
Single Cell test station
• Single cell SOFCs can be tested in various operating conditions and fuel feeds.
•IV curves for various fuel mixes can be obtained which can be used to analyze the effect of fuel composition on the cell performance.
•Short term experiments or long term endurance tests can be carried out.
•Multiple cell test facilities available
1 kW SOFC Stack test station
1kW Stack test station
• Complete stacks of around 1 kW power level can be tested with a variety of fuel flows which can be set to desired concentrations.
•I-V curves for various conditions can be obtained and longevity tests can also be performed to observe stack degradation behavior.
Impedance Spectroscopy
Electrode (Impedance) test stations
•Electrodes can be tested in this setup to provide details about the electrochemical behavior of the anodes/cathodes.
• Electrochemical impedance contributions from diffusion, reactions etc can be evaluated.
•Multiple impedance test stations available.
Computational tools and CFD
Gas cleaning set-ups
Gas cleaning
• (Left) 40 l/min GCU with a lowest gas cleaning temperature of 350 0C for testing SOFC stacks of 1 kW power level using gasified biomass. The unit is also transportable. • (Right) 2 l/min GCU with a lowest gas cleaning temperature of 600 0C for 50W SOFCs using gasified biomass. A parallel gas flow stream for testing independent sorbents separately in another reactor, e.g. tar catalytic reforming is also possible with the set-up. An SOFC (single cell) test unit is integrated.
•Stack development and testing
•Gasifier - SOFC systems
•Numerical tools to simulate SOFCs
•Fuel Gas Cleaning
