(PRESS RELEASE) A little strain goes a long way in reducing fuel cell performance

(PRESS RELEASE) A little strain goes a long way in reducing fuel cell performance

As announced in the recent press release from Kyushu University, Prof. Yoshihiro Yamazaki from Q-PIT and his colleague Prof. Junji Hyodo reported that strain caused by just a 2% reduction in the distance between atoms when deposited on a surface leads to a whopping 99.999% decrease in the speed at which the materials conduct hydrogen ions, significantly reducing the performance of solid oxide fuel cells.

Research result at glance

When yttrium-doped barium zirconate (BZY20) is deposited on an electrode, the atoms near the surface are compressed from their ideal position. This in-plane compressive strain increases the barrier to proton diffusion, thus reducing proton conductivity and reducing performance to levels that match reported values for actual solid oxide fuel cells.

The full press release can be found on the Kyushu University homepage
