Abstract: A fuel cell includes a plurality of unit cells disposed in a stack. Each unit cell includes a membrane electrode assembly (MEA) having an anode and a cathode and a bipolar plate having a cathode side defining a recessed pocket in fluid communication with an air port, an anode side, and coolant channels between the cathode and anode sides. The bipolar plate is disposed against the MEA such that the cathode is disposed over the pocket. A flow guide is disposed in the pocket with a front side facing the MEA and a back side facing a bottom of the pocket. The flow guide has a plurality of embossments.

Abstract: The present disclosure discloses a method for measuring a mudflat elevation based on remotely sensed water content, comprising steps of: measuring a spectral value of a soil surface in a mudflat area using a full-band spectrometer, analyzing a relationship between the spectral value and a soil water content of the mudflat area; building a remotely sensed water content retrieval model using a statistical correlation method; selecting a water sensitive waveband in the remote sensing data, and retrieving the soil water content of the mudflat area; analyzing a relationship between the soil water content and the mudflat likewise using the statistical correlation method; building a relational model between the mudflat water content and an elevation, and applying the model to a satellite image to obtain the mudflat elevation.
