Product Specifications of HP Stacks
High Performance (HP)
HP stacks are especially suitable for dynamic operation and designed for high current density capability up to 230 A. This stack fulfills temporary demands for high power output and thus saves on cost and footprint by limiting the number of stacks needed within the power system. The lifetime of the stack depends heavily on the Balance-of-Plant system and the mode of operation, where >4,500 operational hours and >1250 start-stop cycles can typically be expected for HP stacks. Power outputs as specified below may be observed at Beginning of Life.
