1. A hydrogen refueling station comprising:a portable enclosure;at least one feed line whereinto hydrogen can flow;a hydrogen producing subsystem, which has at least a hydrogen producing unit and a hydrogen cooling unit, connected at one end to the feed line;at least one compressor means, within the enclose, connected to at least one feed line downstream from the hydrogen producing subsystem;one or more hydrogen storage tanks, within the enclosure, connected to at least one feed line downstream from at least one compressor means;at least one control valve connected to at least one feed line;at least one reversible connector, whereby hydrogen from at least one hydrogen storage tank can be dispensed;at least one cooling means, wherethrough hydrogen can flow; and,at least one system controller to control at least one control valve, at least one compressor means, and the hydrogen producing subsystem whereby the flow of hydrogen within the refueling station is affected. 2. The hydrogen refueling station of claim 1 wherein the portable enclosure is a trailer. 3. The hydrogen refueling station of claim 1 wherein the hydrogen producing unit is a KOH electrolyzer. 4. The hydrogen refueling station of claim 3 wherein the source of electrical power for the KOH electrolyzer is selected from the group consisting of turbines, wind, solar, and hydroelectric. 5. The hydrogen refueling station of claim 1 further comprising a tank of pressurized inert gas connected to at least one feed line; whereby introduction of the inert gas into the feed line will purge at least a portion of the feed line and/or the reversible connector. 6. The hydrogen refueling station of claim 1 wherein the portable enclosure is removable from a trailer. 7. A hydrogen refueling station comprising:a portable enclosure;at least one feed line whereinto hydrogen can flow;a hydrogen producing subsystem, which has at least a hydrogen producing unit and a cooling unit, connected at one end to the feed line;at least one compressor means, within the enclosure connected to at least one feed line;one or more hydrogen storage tanks, within the enclosure, connected to at least one feed line downstream from at lest one compressor means;at least one control valve connected to at least one feed line;at least one reversible connector, whereby hydrogen from at least one hydrogen storage tank can be dispensed;at least one cooling means, wherethrough hydrogen can flow;at least one system controller to control at least one control valve or at least one compressor means, whereby the flow of hydrogen within the refueling station is affected; anda second system controller to control the hydrogen producing subsystem. 8. The hydrogen refueling station of claim 7 wherein the portable enclosure is a trailer. 9. The hydrogen refueling station of claim 7 wherein the hydrogen producing unit is a KOH electrolyzer. 10. The hydrogen refueling station of claim 9 wherein the source of electrical power for the KOH electrolyzer is selected from the group consisting of turbines, wind, solar, and hydroelectric. 11. The hydrogen refueling station of claim 7 wherein the portable enclosure is a trailer. 12. The hydrogen refueling station of claim 7 wherein the portable enclosure is removable from a trailer. 13. The hydrogen refueling station of claim 7 further comprising a tank of pressurized inert gas connected to at least one feed line; whereby introduction of the inert gas into the feed line will purge at least a portion of the feed line and/or the reversible connector.
