An electrochemical cell system comprises: a fuel cell module comprising a fuel
cell outlet, an electrolysis module comprising an electrolysis water inlet in fluid
communication with a water storage device and a hydrogen gas outlet in fluid communication
with a hydrogen storage device, and a drainage system disposed downstream of the
fuel cell hydrogen outlet and upstream of the water storage device and configured
to remove water from the electrochemical cell system upon water within the water
storage device attaining a selected level.
