Determine the minimum hydrogen flow rate (in nlpm) supplied to a single fuel cell to produce 103 Amps of current. 0.87 nlpm 0.139 nlpm 0.72 nlpm 5.3 nlpm

Solution

Flow rate= I/(2*F) mole/s

Where I= current=103 A, F= Faraday constant= 96485

Flow rate= 103/(2*96485 . mole/s

Flow rate= 103*22.4*60/(2*96485) lpm

=0.717 lpm
