摘要

A container for both a liquid hydrogen fuel and a substance to be hydrogenated. The container comprises a first containing portion ( 29 ) and a second containing portion ( 33 ). The first containing portion contains a liquid hydrogen fuel ( 27 ) obtained by hydrogenating a substance ( 25 ) to be hydrogenated. The second containing portion contains either a substance to be hydrogenated or a substance to be hydrogenated which remains after a liquid hydrogen fuel is dehydrogenated. The capacity of the first containing portion and the capacity of the second containing portion are respectively variable so that the total of the capacities is constant.
