发明名称	Gas distribution in fuel cells uses parallel channels with alternating flow to provide homogeneous moisture distribution
摘要	Fuel cells are produced with a base that is formed with a number of rectangular section parallel channels (2) separated by barriers (1). Each channel has an inlet for gas (3) and an outlet (4). The inlets and outlets are in opposite directions for adjacent channels so to obtain a homogeneous distribution of moisture within the cell.
