摘要： Methods and devices for generating power using PEM fuel cell power systems comprising a rotary bed reactor for hydrogen generation are disclosed. Hydrogen is generated by the hydrolysis of fuels such as lithium aluminum hydride and mixtures thereof. Water required for hydrolysis may be captured from the fuel cell exhaust. Water is preferably fed to the reactor in the form of a mist generated by an atomizer. An exemplary 750 We-h, 400 We PEM fuel cell power system may be characterized by a specific energy of about 550 We-h/kg and a specific power of about 290 We/kg.

摘要： The present disclosure provides fuel cell units formed from a plurality of flow plate assemblies disposed in a stack configuration, with adjacent flow plate assemblies in the stack configuration disposed at an offset angle relative to each other. Fuel cell stacks can be formed from a plurality of the fuel cell units placed into a stack aligned with each other with no offset. The present disclosure also provides for methods of forming the fuel cell units, fuel cell stacks, and fuel cell systems containing the former.

摘要： The disclosure relates to a fuel cell stack and corresponding method of operating the fuel cell stack. The method comprises: determining a maximum allowable current that may be drawn from the fuel cell stack; repeatedly determining a magnitude of change to the prevailing maximum allowable current based on a prevailing allowable current ramp rate and an actual measured current of the fuel cell stack; updating the maximum allowable current according to the periodically determined magnitude of change; and controlling operating parameters of the fuel cell stack according to the prevailing maximum allowable current.

摘要： A fuel cell system comprises an electrochemical fuel cell stack for generating electrical power. A load circuit is switchably coupled to the fuel cell stack for periodically receiving a discharge current from the fuel cell stack during an energy dissipation phase, such as an air stall operation for conditioning the fuel cell stack. A protection circuit is coupled to the load circuit, configured to monitor a cumulative energy dissipation level during an energy dissipation phase and to abort an energy dissipation phase if the cumulative energy level reaches a predetermined threshold. In this way, lower specification resistor components can be used for stack conditioning.
