Abstract
This disclosure relates to a hydrogen fuel cell stack with one or more hydrogen fuel cell (102) having in turn a proton exchange membrane (104), a hydrogen reaction layer (112) and an oxygen reaction layer (116) within a pair of bipolar plates (106). At least a bipolar plate (106) comprises a channel (108) inside for hydrogen inflow. Additionally, this disclosure relates to a method of upgrading a hydrogen fuel cell stack, said method comprising inserting a channel (108) for hydrogen inflow inside at least a bipolar plate (106).
