Students amazed by both low-tech and advanced science

You take an ordinary printer, adds a specially developed driver and voila, you can print 100 times on one square centimeter and create your very own miniature tape casting.

Simple, effective and a bit of an eye opener for the two students David Marhauer-Nimb and Anne Sofie Lütken from MSc Sustainable Energy at the Technical University of Denmark in Lyngby.

They form one of three teams, who these days participate in three weeks of experimental courses at DTU Energy Conversion, and they are both happy to finally be able to see how things work in reality.

"It always amazes you how something very advanced sometimes can done very low-tech," says Anne Sofie Lütken.

"We've had 13-week course on hydrogen and fuel cells, but one thing is theory, another thing is practice."

Her study companion nods. The theoretical course in hydrogen and fuel cells was heavy and theoretical, in fact so heavy and theoretically, that they are among the small crowd that did not drop out along the way.

It pays off now.

"It's nice to see how it works in reality. We have both been on lab tour at DTU in Lyngby, but it is only now, when we see the high-tech equipment in use, that we are able to the processes in both tape casting and sintering, "says David Marhauer -Nimb.

The two students tell how they have read lots of scientific journals. But you never know for sure, what is really important and what isn’t in the articles.

"Things that looks very complicated in the articles can suddenly become very tangible. Now we understand why sintering takes time, and why you don’t want to heat the material too fast and things like that. "

The two graduate students are studying stabilization of slurries, another team experiments with cell test and a third team work on 3D printing of electrolytes and electrodes. And although there is a long way from Lyngby to Risø, the students find the combination of beautiful natural surroundings and a highly competent research environment very attractive.

"It is lovely informal here, but you clearly feel that the research is taken very seriously. Risø is not so easily accessible, but it is definitely a place where I would like to do my thesis, "says Anne Sofie Lütken.

David Marhauer-Nimb nods. The distance is not a deterrent if you end up among those who actually know something about fuel cells, a subject both students are very passionate about.
