Depending on the degree of fuel starvation, local and overall starvation affect durability in totally different ways. Here, it is worth noting that they can be mitigated or even eliminated by optimizing the control of the gas supply [230,255], the reactant amount [255], the gas flow field [256], and the loading speed in the load-up process. In addition, adding a hydrogen reservoir at the hydrogen outlet of the stack [257,258] has also been reported to be effective.
