Holistic design of fuel cell electrocatalysts for the least power applications
Project Director: Dr. Mihaela Florea
The CATALEAST proposal allows bringing together diverse backgrounds of the partners and creating a
synergy between self-experiences to be applied to new fields of modern catalysis and fuel cells. The project
will certainly bring an effective added value to the sustainable development for all partners. This experience
might be a key for further common actions between all partners, and also it will give the opportunity for
the young researchers to complete their qualifications working on this subject. Instrumental techniques at
the Romanian (P2, P3) and Spanish (P4) partners could become available to the Hungarian partner (P1)
for catalyst characterization. The Spanish partner (P4) would have a new type of catalysts for MEA
construction, which would be provided by the Hungarian (P1) and Romanian (P2) partners. Both the
Spanish (P4) and Romanian (P2, P3) partners could acquire knowledge on the field of high throughput
techniques and combinatorial methods used by the Hungarian partner (P1), which is particularly useful in
the research of material science with a large number of samples. Since both the Hungarian (P1) and the
Romanian partners (P2) are able to reach only the synthesis of the electrocatalysts of the fuel cells, the
Spanish (P4) expertise gives them the opportunity to compile MEA and produce micro fuel cells from the
novel materials. Thus, through transnational cooperation, research results can be brought closer to practical
Role in the project: Partner P3 (National Institute of Materials Physics) will be responsible for the physicochemical characterization of the most promising ORR and HOR catalysts as an input coming from the high throughput electrochemical screening performed by the P1.
Relevant expertise: The team’s competences are in the field of chemistry, catalysis and materials physics. As presented in the Annex 1 the team possesses expertise in the field of thematic area as well in the field of the project.
Added value: A deep understanding through characterization of the new materials; recommendation of ways to make the materials more competitive.

FIRST STAGE 2019
During the first stage of the project, over 10 samples were prepared using different preparation methods. It has been observed that the preparation method influences the type of crystalline phase present in the final material. Also, the amount of dopant influences the crystallinity of the sample, so that with increasing the amount of dopant the crystallinity decreases, as presented in Figure 1:
