Abstract |
For the past decades scientific research in the energy sector has been focused on
utilization of sustainable energy sources, while developing new and more efficient energy
production systems. Fuel cells are galvanic cells capable of electrochemical energy conversion, and
are currently being studied and implemented as a promising solution. One major issue for large
scale application of these devices is scalability, cost and complexity of fabrication. A proposed
manufacturing solution is the deployment of printing techniques to fabricate thin film electrodes of
fuel cells. In this study, the use of inkjet printing is considered as a deposition method for electrodes
fabrication, however, due to the novelty of this technique, additional research is needed for the
optimisation of ink development and film deposition of materials used in fuel cells. Currently, the
main challenge of this interdisciplinary study on ink development is to produce suspensions of these
complex metal oxides, that can be both stable over time and inkjet printable. Here, the study of fuel
cell materials and formulated suspensions is presented. More specifically this thesis will include
results on the development and optimisation of oxide nanoparticle suspensions, such as
agglomeration of particles, suspension stability, storage tests, thermal degradation, temperature
dependent rheological characteristics, surface tension, and ink-to-substrate interactions. Such
properties are of great importance when formulating particle suspensions to be used as inks in the
fabrication of printed fuel cells.
