摘要： A redox flow battery (“CRB”) performs as an energy storage system and has a negative electrode that directly utilizes CO2 in the battery charge step as an active species instead of metals. The CRB also has a positive electrode utilizing a metallic or non-metallic redox species, and a cation exchange membrane in between the negative and positive electrodes. The negative electrode comprises a porous base layer, a porous intermediate layer containing a metal oxide and a bi-functional catalyst layer for electrochemical reduction of CO2 or carbonate to formate and for formate oxidation to either carbonate or CO2. The bi-functional catalyst can be a PdSn based catalyst, such as PdSn, PdSnIn, and PdSnPb. The metal oxide in the intermediate layer acts as a catalyst support and can be a non-Platinum group metal (PGM) oxide, such as LaCoO3 or LaNiO3.

摘要： In one or more embodiments, a disclosed method for cooling a vehicle involves routing, by a bypass line, boil-off of a cryogenic fuel of the vehicle past a cold plate to cool a subsystem mounted proximate the cold plate. The method further involves purging the boil-off in a direction away from the vehicle, after the boil-off passes the cold plate. In one or more embodiments, the cryogenic fuel involves liquid hydrogen (LH2), liquid oxygen (LO2), and/or liquid methane (LCH4). In at least one embodiment, the boil-off of the cryogenic fuel involves gaseous hydrogen (GH2), gaseous oxygen (GO2), and/or gaseous methane (GCH4). The vehicle is a space vehicle, an airborne vehicle, a terrestrial vehicle, or a marine vehicle. In at least one embodiment, the vehicle is a fuel cell vehicle (FCV).
