hydrogen consumption rate :

<div><span style="font-family:"Times New

caclulation usign the fommula i found a value of 0.183
mol/s wich correspond to 14.834 Nm3/h</span></div>
<div><span style="font-family:"Times New
Roman",serif;font-size:12pt">but in simulation i'm
getting a complete different value (around 100 Nm3/h)</span></div>
