Abstract: A battery interconnect may include a desired current capacity, integrated fusible links, and be manufacturable using cost effective techniques. In some embodiments, a battery interconnect includes a busbar and relatively thinner links. A busbar carries larger currents and accordingly its cross-sectional areas are relatively larger to reduce ohmic losses. A link carries a much smaller current, and a fusible link is configured to break the circuit when the current is above a threshold, thus requiring a relatively small cross-sectional area. These sometime disparate length scales are addressed using several techniques such as layering a busbar and a foil sheet and pressing portions of a busbar to form the links. The links can be affixed to a plurality of battery cells to connect the cells in parallel or series.

Abstract: The present disclosure provides methods for turbine-based energy recovery from exhaust streams in fuel cell systems. The fuel cell systems can include an expansion turbine (200) arranged to capture electrical energy from cathode exhaust streams. The cathode exhaust streams (151a, 151b, 151c) can be flowed through an intercooler (250) to be preheated prior to entering the expansion turbine (200), with heat added by transferring heat from a compressed air flow. The methods can include operating the fuel cell system in a temperature-boost mode that includes reducing fan operation related to a condenser to reduce liquid recapture from an exhaust stream and increase exhaust stream temperature for use in turbine-based energy recovery. The temperature-boost mode can be controlled to limit the operation time based on coolant fluid levels in the fuel cell system.
