摘要： An electrochemical cell is disclosed comprising, a first flow structure, a second flow structure, and a membrane electrode assembly disposed between the first and second flow structures. The electrochemical cell further comprises a pair of bipolar plates, wherein the first flow structure, the second flow structure, and the membrane electrode assembly are positioned between the pair of bipolar plates. The electrochemical cell also includes a spring mechanism, wherein the spring mechanism is disposed between the first flow structure and the bipolar plate adjacent to the first flow structure, and applies a pressure on the first flow structure in a direction substantially toward the membrane electrode assembly.

摘要： The present disclosure is directed towards a method and a system for monitoring the performance of an electrochemical cell stack. Monitoring can be performed remotely by measuring the voltage across the stack, and comparing the measured values to predetermined reference values to determine the condition of the stack. Monitoring of the stack voltage enables detection of performance decay, which in turn enables preemptive repair of the stack prior to catastrophic failure.

摘要： The present disclosure is directed towards the design of electrochemical cells for use in high pressure or high differential pressure operations. The electrochemical cells of the present disclosure have non-circular external pressure boundaries, i.e., the cells have non-circular profiles. In such cells, the internal fluid pressure during operation is balanced by the axial tensile forces developed in the bipolar plates, which prevent the external pressure boundaries of the cells from flexing or deforming. That is, the bipolar plates are configured to function as tension members during operation of the cells. To function as an effective tension member, the thickness of a particular bipolar plate is determined based on the yield strength of the material selected for fabricating the bipolar plate, the internal fluid pressure in the flow structure adjacent to the bipolar plate, and the thickness of the adjacent flow structure.
摘要翻译：本公开涉及用于高压或高压差操作的电化学电池的设计。本公开的电化学电池具有非圆形外部压力边界，即，电池具有非圆形轮廓。在这样的电池中，操作期间的内部流体压力由双极板中产生的轴向张力平衡，这阻止了电池的外部压力边界的弯曲或变形。也就是说，双极板被配置为在电池工作期间用作张力构件。为了起到有效的张力构件的作用，特定双极板的厚度基于选择用于制造双极板的材料的屈服强度，与双极板相邻的流动结构中的内部流体压力和相邻的流动结构。
