abstract = {Electrochemical cells contain electrically conductive
components, which causes various problems if such a cell is
analyzed during operation in an EPR resonator. The optimum
cell design strongly depends on the application and it is
necessary to make certain compromises that need to be
individually arranged. Rapid prototyping presents a
straightforward option to implement a variable cell design
that can be easily adapted to changing requirements. In this
communication, it is demonstrated that sample containers
produced by 3D printing are suitable for EPR applications,
with a particular emphasis on electrochemical applications.
The housing of a high temperature polymer electrolyte fuel
cell (HT-PEFC) with a phosphoric acid doped
polybenzimidazole membrane was prepared from polycarbonate
by 3D printing. Using a custom glass Dewar, this fuel cell
could be operated at temperatures up to 140 °C in a
standard EPR cavity. The carbon-based gas diffusion layer
showed an EPR signal with a characteristic Dysonian line
shape, whose evolution could be monitored in-operando in a
non-invasive manner.},
