摘要： A redox cell rebalance system is provided. In some embodiments, the rebalance system includes electrochemical cell and a photochemical cell. In some embodiments, the photochemical cell contains a source of ultraviolet radiation for producing HCl from H2 and Cl2 generated by the system. The HCl product may be collected or circulated back through the system for the rebalancing of electrolytes. A rebalance cell for use in a rebalance system is also provided. In some embodiments, the rebalance cell is the combination of an electrochemical cell and a photochemical cell. In some embodiments, a source of ultraviolet radiation is housed in the cathode compartment of the rebalance cell. In some embodiments, the source of ultraviolet radiation is used to effect the formation of HCl from H2 and Cl2 present in the rebalance cell. The HCl is dissolved in aqueous electrolytes contained in the rebalance cell, which can subsequently be circulated through a rebalance system for the rebalancing of redox cells.

摘要： A system and method in which a high temperature fuel cell stack exhaust stream is recycled back into the fuel inlet stream of the high temperature fuel cell stack. The recycled stream may be sent to a carbon dioxide separation device which separates carbon dioxide from the fuel exhaust stream. The carbon dioxide separation device may be a carbon dioxide trap, an electrochemical carbon dioxide separator, or a membrane separator. A water separator may be used in conjunction with the carbon dioxide separation device or used separately to continuously remove water from the recycled stream.

摘要： The invention provides an anode gas diffusion layer for a fuel cell and methods for preparation and use thereof. In particular, a hydrophilic anode gas diffusion layer promotes water transfer through the fuel cell. As an example, in one aspect, the invention provides a fuel cell system, including a fuel cell with an anode gas diffusion layer. The anode gas diffusion layer has a contact angle with water less than 140° (e.g., in some cases less than 120° or less than 100°). In another aspect, the invention provides a gas diffusion layer for a hydrogen electrode of a PEM fuel cell that includes a carbon fiber media having a water contact angle of less than 140°.
