Disclosed is an aircraft resource management system. The system may include at least one fuel cell cluster having at least one fuel cell system configured to receive and convert a hydrogen input comprising hydrogen and an oxygen input comprising a fluid having an initial oxygen content so as to yield a number of products. The products can include water, thermal energy, an oxygen-depleted product comprising the fluid having a second oxygen content lower than the initial oxygen content, and electrical power. The system may include at least one load cluster with at least one load configured to utilize at least one product of the fuel cell cluster. The system may compare a demand level of the load cluster with a supply level of the fuel cell cluster and manage operating levels of the fuel cell cluster based at least in part on the comparison.
