Abstract: According to one aspect, a system for resource management may perform receiving a total resource request, a vector of two or more maximum available resources associated with two or more corresponding resource providers, and a number of resource providers and calculating an individual resource request for each of the two or more resource providers by iteratively comparing the vector of two or more maximum available resources with a vector of a current average resource residual, taking a minimum between those vectors as a running tally for the individual resource requests, and recalculating the current average resource residual.

Abstract: A fuel cell power plant system may include two or more power units and a fuel cell power plant controller. The two or more power units may be electrically connected. Each one of the two or more power units may include two or more fuel cell systems. The fuel cell power plant controller may be electrically connected to the two or more power units and may include a user control circuitry and a monitoring circuitry. The user control circuitry may control a mode of operation of the fuel cell power plant system to be run in an operation mode, a standby mode, a maintenance mode, or an emergency stopped mode. The monitoring circuitry may monitor the two or more power units of the fuel cell power plant system for one or more fault conditions, one or more alarms, or an amount of energy produced.

Abstract: A fuel cell power plant system may include two or more electrically connected power units, two or more voltage channels, and a fuel cell power plant controller. Each one of the two or more power units may include two or more fuel cell systems. The two or more voltage channels may be respectively connected to the two or more power units. The fuel cell power plant controller may be electrically connected to the two or more power units.

Abstract: A fuel cell power plant cooling system may include a power unit coolant supply line configured to receive a coolant, two or more fuel cell system coolant supply lines connected to the power unit coolant supply line and configured to receive coolant from the power unit coolant supply line, two or more fuel cell systems configured to be cooled by the two or more fuel cell system coolant supply lines, respectively, two or more fuel cell system return supply lines connected to the two or more fuel cell system coolant supply lines, respectively, and configured to receive coolant from the two or more fuel cell system coolant supply lines, and a power unit return supply line connected to the two or more fuel cell system return supply lines and configured to receive coolant from the two or more fuel cell system return supply lines, respectively.

Abstract: A fuel cell power plant system may include a fuel supply line, two or more fuel cell system fuel supply lines, and two or more power units. The fuel supply line may be configured to receive fuel. The two or more fuel cell system fuel supply lines may be connected to the fuel supply line and may be configured to receive fuel from the fuel supply line. The two or more power units may be configured to be fueled by the two or more fuel cell system fuel supply lines, respectively.

Abstract: A heat exchanger for a fuel cell power plant system may include a first loop and a second loop. For the first loop, a first coolant may be passed through a fuel cell stack, a thermostat, a first portion of a first plate of the heat exchanger, and a fuel cell pump. For the second loop, a second coolant may be passed through a second portion of the first plate of the heat exchanger.
