Dataset language: English 2. Abstract: This dataset gathers the initial formation and the evolution of water content and distribution, as well as water evacuation, within a lung-inspired PEM fuel cell with a 50 cm2 active area for various operating conditions such as cell pressure, relative humidity of the reactant (anode and cathode), temperature, and cell current density. Neutron imaging was used as it has been shown to be an affective technique for quantitative analysis of water distributions. A series of videos compiling the individual images obtained through neutron imaging, showing the water distribution evolution are presented. Numerical and graphical compilation of the amount of water in a cell through time in different regions of the cell and for a total of 10 experiments are provided. It comprises the water accumulation in stationary and the water distribution in transient state. 3. Keywords: PEMFC fuel cell; water distribution; water transport; neutron imaging 4.
