Thermal behaviour of ZrCo getter beds during hydrogen absorption at variable flow rates and concentrations

• Higher H 2 concentration/flow over ZrCo bed leads to higher absorption rate and higher peak temperature. • Higher flow drives temperature higher than a lower flow since more H 2 is arriving/ sec . • The peak bed temperature remains well below 400 °C even under pure high H 2 /flow. • Absorption is temperature driven and the peak temperature tracks the reaction time roughly exponentially. • ZrCo H 2 absorption capacity remains essentially constant over ∼ 40 cycles indicating good durability. • B
