Coalescence free moisture

The end use defines the quality and quantity of the gas needed. For our purposes, the end use for the hydrogen generated is a fuel for fuel cells. Most commercial hydrogen generating units incorporate a drying mechanism that removes much of the moisture from the gas. This is not appropriate for a fuel cell system. Free water will be abundant and should be removed by a water filter or series of water filters, but it is not necessary to remove very fine aerosols by coalescer or to use water absorption techniques. The reason is that the hydrogen side of the fuel cell membrane needs to remain hydrated (moist at a certain level) to aid and maintain proton transport for the operation of the fuel cell.
