Alkaline Water Electrolyzer Stack - 6 Cell

The development of high-efficiency nickel electrodes based on the core technology reduces the system production cost and generates hydrogen through the high-yielding rate per input power, and this technology has a long life cycle activating over 10,000 hours (for nickel based electrodes).  The estimated lifetime for the alkaline electrolyzer stack (or individual cells present in the stack hardware) is 6000 operational hours.  This alkaline electrolyzer stack requires a caustic solution of 30 wt% KOH for its efficient operation.
