Method of operating gas storage and supply system

Disclosed is a process of supplying a gaseous fuel from a fuel storage vessel to a secondary device.

Fuel supply system with a gas adsorption device

A method of fuel cell stack humidification is provided incorporating the use of an accumulation device. The method provides for feeding back humid anode exhaust gas of the fuel cell stack to the fuel cell inlet and switching the anode inlet and outlet of the fuel cell stack for achieving better homogeneity of humidity along the fuel cell channels.
