Abstract: A landscape management method is disclosed. The method may include: populating an area of a map with information about a plant, for example a grass or a lawn, associated with the area; receiving from a sensor located in the zone, first data regarding the plant; comparing automatically, the first data with reference data of a plant of a same type as the plant, and making a determination, based on the comparing, regarding a landscape management action for the area; and transmitting a signal indicating the landscape management action for the area according to the determination. The comparing may entail image processing to determine vigor of the plant. Vigor may be determined by judging leaf width, coloration, or folding of leaves or blades with respect to a stolon or midvein or by other changes in leaf geometry. Repeated data sampling to identify and judge trends in plant health and condition may also be used.

Abstract: A bipolar plate assembly includes at least one bipolar plate and an insert member in engagement with the at least one bipolar plate. The insert member has an encapsulant encapsulating at least a portion thereof.

Abstract: A bipolar plate assembly includes a first bipolar plate and a second bipolar plate. The second bipolar plate has a recess. An insert member is disposed between the first and second bipolar plates and within the recess of the second bipolar plate.

Abstract: A bipolar plate assembly includes a first bipolar plate and a second bipolar plate having a recess therein. An insert member is disposed between and in engagement with the first and second bipolar plates and located in the recess in the second bipolar plate. An adjustment member adjusts the engagement between the insert member and at least one of the first and second bipolar plates.

Abstract: A bipolar plate assembly includes at least one bipolar plate and at least one insert member configured for face-to-face engagement with the at least one bipolar plate. The at least one insert member has a preformed cutout.

Abstract: Disclosed are fuel cell stacks incorporating heat exchangers capable of also acting as members to compress the fuel cell stack. Heat exchange through conduction is enabled by placing the heat exchanger into contact with the edges of the bipolar plates. A compressive force within the fuel cell stack is achieved by placing the heat exchanger in tension between the endplates at the opposite ends of the fuel cell stack.

Abstract: A bipolar plate assembly includes a first material and a second material. The second material has an in-plane thermal conductivity greater than the first material. The second material has a width and a thickness. A ratio of the width to the thickness of the second material is between 50 and 400.

Abstract: A regenerative fuel cell/electrolyzer stack. The regenerative fuel cell/electrolyzer stack may comprise a fuel cell electrode assembly comprising first and second fuel cell electrodes, as well as a fuel cell electrolyte. The regenerative fuel cell/electrolyzer stack may also comprise an an electrolyzer electrode assembly comprising first and second electrolyzer electrodes. A conductive plate may be positioned between the fuel cell electrode assembly and the electrolyzer electrode assembly. The conductive plate may comprise a first surface facing the first fuel cell electrode and a second surface facing the first electrolyzer electrode. The first surface may comprise at least one flow path open to the first fuel cell electrode, and the second surface may comprise at least one flow path open to the first electrolyzer electrode.
