In particular, the tradeoffs between water production and removal through transport or evaporation are highlighted, with a focus on low-temperature performance. For the latter, a case study of an ultra-thin catalyst layer is undergone to explore how various material properties alter the steady-state and startup performance of a cell. The findings provide understanding and guidance to optimize fuel-cell performance with thin electrodes.}, year = {2016}, journal = {Journal of The Electrochemical Society}, volume = {163}, pages = {F691 - F703}, month = {06/2016}, issn = {0013-4651}, doi = {10.1149/2.1161607jes}, language = {eng}, }
