At nominal operation, the current density for a single cell of the electrolyzer stack is 0.40 $\frac{A}{c}{m}^{2}$. The nominal operating temperature of the water electrolyzer stack is ${70}^{\circ }$ C and pressure 1 bar. The voltage over a single electrolytic cell is 1.96 V at nominal load and 1.78 V at 50% of nominal load. The Faraday efficiency of the water electrolyzer stack is 95% at nominal current density, but at 50% of nominal load, the Faraday efficiency decreases to 80%. (Give your answer to at least three significant digits.) Calculate the nominal stack voltage: Answer in V Calculate the nominal stack current: Answer in A Calculate the nominal power on the water electrolyzer stack: Answer in kW Upper Level Math Answered Lipossig 2020-11-14 ### What is the future of$2200 invested for nine months at 4.25% compounded semiannually?
