Hydrogen Evolution – Where Did The Value In IEEE Std 484TM Come From?

IEEE Std 484TM – 2002 states that the maximum hydrogen evolution rate for an electrochemical cell is 0.000269 ft3/min per charging ampere per cell at 77 °F and standard pressure (29.92 in Hg) or 0.127 mL/s per charging ampere per cell at 25 °C and standard pressure (760 mm Hg).  This has been in the standard since it was first …
