      abstract     = {This study evaluates the role of microstructure for the
                      conductivity of BaZrO3-based protonic conductors. Bulk
                      conductivity was found to be the limiting conductivity
                      contribution in BaZr0.8Y0.2O3-δ (BZY20) and
                      BaZr0.7Ce0.2Y0.1O3-δ (BZCY72) at operating temperatures.
                      The effective grain boundary conductivity only dominates the
                      total conductivity below a crossover point (200 °C for
                      BZY20, 150 °C for BZCY72). The crossover point was
                      determined by using a well-calibrated electrochemical
                      impedance spectroscopy setup to measure from 600 °C to 50
                      °C with up to 10 MHz. As such, bulk and grain boundary
                      could be fitted separately up to 350 °C instead of 200 °C,
                      as often seen in literature. According to these results, the
                      impact of grain boundaries on the total conductivity of
                      BZY20 and BZCY72 at operating temperature might be less than
                      assumed. Therefore, research should not only focus on
                      increasing the conductivity of the grain boundary, but also
                      on maximizing the bulk conductivity.},
