▎ 摘　　要

NOVELTY - The utility model relates to an enhancing device for filtering hydrogen to produce a hydrogen fuel battery using graphene film, belonging to the technical field of new energy application. A mixed gas containing hydrogen is compressed in a gas compression device, driving the compressed mixed gas containing hydrogen through the gas pipeline to enter into a graphene film hydrogen filtering device. the mixed gas containing hydrogen at the graphene film hydrogen filtering device in meeting the first layer filtering hydrogen graphene film, molecular weight of hydrogen gas more than 40 cannot pass through the first filter hydrogen layer graphene film, then the second layer filtering hydrogen graphene film, molecular weight of hydrogen gas more than 17.5 cannot pass through the second layer filtering hydrogen graphene film. the third layer filtering hydrogen graphene film, molecular weight of hydrogen gas more than 2.5 cannot pass through the third layer filtering hydrogen graphene film. molecular weight of 2.016 hydrogen molecule continuously through three layers of filtering hydrogen graphene film to produce pure hydrogen to produce hydrogen fuel and a hydrogen fuel cell.
