Abstract
A hydrogen dispenser comprises a programmable controller and a user interface operably connected to the programmable controller. The programmable controller has a plurality of user-selectable hydrogen dispensing rate algorithms. The user interface offers the plurality of user-selectable hydrogen dispensing rate algorithms and is used for setting a user-selected dispensing rate algorithm from among the plurality of user-selectable hydrogen dispensing rate algorithms.
Claims10
A hydrogen dispenser comprising:
- a programmable controller having a plurality of user-selectable hydrogen dispensing rate algorithms for dispensing the hydrogen, the plurality of user-selectable hydrogen dispensing rate algorithms used by the programmable controller for effecting instantaneous hydrogen dispensing rate during dispensing;
- and a user interface offering the plurality of user-selectable hydrogen dispensing rate algorithms, the user interface operably connected to the programmable controller for setting a user-selected dispensing rate algorithm from among the plurality of user-selectable hydrogen dispensing rate algorithms;
- wherein the plurality of user-selectable hydrogen dispensing rate algorithms are user-selectable wherein a user enters information into the user interface to select from preset alternative hydrogen dispensing rate algorithms or enters a value for the hydrogen dispensing rate algorithm;
- and wherein the plurality of user-selectable hydrogen dispensing rate algorithms comprises a first dispensing rate algorithm programmed to dispense a first quantity of hydrogen at a first time-averaged dispensing rate for a first time period and a second dispensing rate algorithm programmed to dispense a second quantity of hydrogen at a second time-averaged dispensing rate for a second time period, wherein the first time period is less than the second time period, the first time-averaged dispensing rate is greater than the second time-averaged dispensing rate, and the first quantity of hydrogen is less than the second quantity of hydrogen.
