Fuel cell systems aboard means of transport can be used for generating energy and for producing water. In order to reduce the overall weight of the system, the fuel cell is controlled or regulated in dependence on a current fill level or a limit level of the water tank, as well as a predicted future water consumption. In this way, it may be possible to minimize the water quantity to be stored in the water tank.

Disclosed are activated carbon electrodes fabricated according to a pore mouth diameter mixture profile that is optimized for a given electrochemical application. In a given pore mouth diameter mixture profile, the pore mouth diameter and conductivity of activated carbon are tightly controlled and provide unexpected long-term charging/discharging (aka cycling) performance. A given pore mouth diameter mixture profile optimizes a mixture of pore mouth diameters for a given electrochemical application, such as energy storage, desalination, deionization, hydrolysis, and dialysis, inter alia.
