cell combined with the hydrogen generating apparatus 200 or from a user who inputs the information through a separate input unit the hydrogen generating apparatus of the present invention can have a plurality of the first electrodes 220 and or the second electrodes 230 in the case that a plural number of the first electrode 220 and or the second electrode 230 are disposed it can take a shorter time to generate the demanded amount of hydrogen since the hydrogen generating apparatus 200 can generate more hydrogen per unit time fig3 is a graph showing how the amount of electric current flowing between the first electrode 220 and the second electrode 230 is related to the volume of hydrogen generated on the second electrode 230 here it should be noted that the volume of hydrogen is shown in flow rate measured per minute because not the total volume of generated hydrogen but the flow rate of hydrogen is significant to a fuel cell an experiment for fig3 was conducted under the following conditions the above conditions were used for every graph referred to in describing the present invention fig3 shows a greater flow rate of the hydrogen than a theoretical value based on mathematical formula 1 due to an.
