Abstract:
An autothermal reformer or a catalytic partial oxidizer () receives flow of desulfurized hydrocarbon fuel from a hydrogen desulfurizer (HDS) () through an orifice (). A differential pressure transducer (b) provides a signal () to a fuel-flow differential-pressure schedule () to provide a fuel flow signal () which is () subtracted from fuel command (), to provide a valve position signal from a proportional/integral gain (), being linearized () to control the fuel valve (). The minimum () of actual fuel flow () and fuel flow command () is applied to an air/fuel schedule (). The resulting air flow command is compared with actual air flow () to provide an air flow control signal which is linearized () after proportional/integral gain () to provide air flow command () to a blower (). Differential pressure () across an orifice () is provided to a schedule () which converts to the actual air flow feedback (). A laminar flow restriction () may be warmed by a CPO ().

US Classification:
429450, 429514, 429509, 429508
Abstract:
A fuel cell includes an electrode assembly having an electrolyte between a cathode catalyst and an anode catalyst, and a flow field plate having a channel for delivering a reactant gas to the electrode assembly. The flow field plate includes a channel having a channel inlet. A porous diffusion layer is located between the electrode assembly and the flow field plate. The porous diffusion layer includes a first region near the channel inlet and a second region downstream from the first region relative to the channel inlet. The first region includes a filler material that partially blocks pores of the first region such that the first region has a first porosity and the second region has a second porosity that is greater than the first porosity.

Systems for suppressing adverse exothermic reactions in an energy storage container. One energy storage system includes a container configured to support a plurality of battery cells; a plurality of battery cells disposed inside and supported by the container; an agent supply port attached to the container; and a tube disposed inside the container and having a closed end and an open end. The open end of the tube is in fluid communication with the agent supply port. The tube comprises fusible portions which are designed to melt or soften at a temperature which is lower than the melting or softening temperature of another portion of the tube. In response to melting or softening of the fusible portions of the tube, pressurized exothermic reaction-suppressing agent is distributed inside the container via the tube.

Abstract:
Methods and systems for charging a battery string while protecting against overcharging. One system includes: a pair of disconnect devices; a power distribution bus which is electrically connected to a battery string via the disconnect devices; a battery charger connected to supply battery power to the power distribution bus for charging the battery string; a module monitoring unit configured to sense individual battery cell voltages during charging; a first processor configured to activate one disconnect device to open when the sensed individual battery cell voltages indicate overcharging; a plurality of sensors connected to sense a full-string voltage measured across the battery string and first and second half-string voltages measured across first and second half-strings of the battery string; and a second processor connected to receive sensor data during charging. The second processor is configured to independently activate the second disconnect device to open when the sensor data indicates continued overcharging.

International Classification:
H02J 7/00
Abstract:
Apparatus and methods for mitigating abrupt release of energy due to a short circuit or other fault external to battery modules in a battery pack. Each battery module includes a plurality of weakened fusible links, which may connect an associated cell to a virtual cell busbar or connect dedicated busbars. After the fault has been cleared and faulted battery modules have been bypassed, the battery pack is ready for reconnection to the electrical network to provide power for the load(s). The battery management includes detection and isolation of a fault followed by execution of an algorithm for reconnection of the battery pack to the power distribution system after burnout of the fusible links. In addition, the respective activation times for reconnecting operative (not faulty) modules in a faulty battery string versus reconnecting other operative battery strings in the battery pack are coordinated.

A battery and related methods are described. The battery can include a plurality of battery cell segments. Each of the battery cell segments can include: a positive temperature coefficient (PTC) material whose resistance increases with temperature, an anode segment, a cathode segment, and one or more current limiters. The one or more current limiters of a battery cell segment are configured to conditionally electrically isolate the battery cell segment based on an occurrence of a short circuit within the battery cell segment.
