The invention claimed is: 1. A hydrogen producing method in a hydrogen supplying apparatus, comprising the steps of: adding one or more metals to a hydrogen generating medium stored in a portable cassette means by a coprecipitation method or by an impregnation method, wherein the hydrogen generating medium is Fe or iron oxide, and the one or more metals is not Fe and is not iron oxide and is not Mg; pouring water or water vapor into the portable cassette means via one of at least two passages; and supplying hydrogen from the other of said at least two passages to a hydrogen consuming device, wherein the hydrogen is generated by decomposing the water, and wherein the hydrogen supplying apparatus includes the portable cassette means having the hydrogen generating medium and said at least two passages. 2. The hydrogen producing method according to claim 1, wherein one or more added metals are selected from a group consisting of the fourth family, the fifth family, the sixth family, and the thirteenth family of the Periodic Table for the elements. 3. The hydrogen producing method according to claim 1, wherein the one or more added metals are selected from a group consisting of Ti, Zr, V, Nb, Cr, Mo, Al, and Ga. 4. The hydrogen producing method according to claim 1, wherein the one or more added metals are selected from a group consisting of Sc, Ni, and Cu. 5. A hydrogen supplying apparatus, configured by a portable cassette, which includes a hydrogen generating medium, comprises at least two pipe installing means and at least two pipe units for coupling with the at least two pipe installing means respectively, wherein: a main component of the hydrogen generating medium is iron or iron oxide, to which one or more different metals are added; and the cassette, into which water or water vapor is poured via one of the pipe installing means and one of the pipe units, can supply hydrogen, which is generated by decomposing the water, from the other communicating pipe installing means and the other of the pipe units to a hydrogen consuming device. 6. The hydrogen supplying apparatus according to claim 5, wherein a heater is arranged within the cassette. 7. The hydrogen supplying apparatus according to claim 5, wherein at least one of the pipe units which supplies inert gas or air is arranged in the cassette.
