ABSTRACT:
A system and method of purifying hydrogen gas. The system includes heating elements for heating the hydrogen diffusion cell to a predetermined operational temperature. A preheater is provided for heating unpurified gases that will enter the hydrogen diffusion cell. The unpurified gases are heated to the operational temperature of the hydrogen diffusion cell before entering the hydrogen diffusion cell. In this manner, the inflow of unpurified gases into the hydrogen diffusion cell does not cause any thermal shock to the hydrogen diffusion cell. The incoming unpurified gases are heated in two ways. The unpurified gases are heated in a preheater. The unpurified gases are also heated in a heat exchanger. The heat exchanger recycles the heat from the purified hydrogen gas.
