Abstract: Systems and methods are provided for operating an electrolyzer. The systems and methods include operations comprising: determining that a first electrolytic cell in a first electrolyzer stack is associated with a first set of performance criteria that fails to satisfy one or more operating conditions; identifying a second electrolytic cell that is associated with a second set of performance criteria that satisfies the one or more operating conditions; and bypassing the first electrolytic cell and the second electrolytic cell in response to determining that the first electrolytic cell in the first electrolyzer stack is associated with the first set of performance criteria that fails to satisfy the one or more operating conditions and based on identifying the second electrolytic cell that is associated with the second set of performance criteria that satisfies the one or more operating conditions.

Abstract: An optical system for receiving light scanned from different light origination locations in space can include a Liquid Crystal (LC) waveguide (LCW), including first and second LCW light ports. A beamsteering LC electrode can be included in or coupled to the LCW and can be configured to vary a receiving direction of light received at the second LCW light port in response to a varying electrical input signal applied to the LC electrode to scan receiving of light at the second LCW light port from different light origination locations in space. A photodetector can be optically coupled to the first LCW light port, such as to detect waveguided light from different light origination locations in space received in response to the varying electrical input signal applied to the first LC electrode. Ranger, bright-spot locking, laser detection, direct detect and coherent lidar, wavelength detection, and other techniques and use cases are possible.

Abstract: Described herein are electrochemical impedance spectroscopy (EIS) systems and methods that facilitate the allocation of a single stimulus generator across a number of electrolyzer stacks, each comprising a set of electrochemical cells. By distributing a stimulus signal, impedance data of the cells in each electrolyzer stack may be measured, e.g., to evaluate their condition or the condition of the stack without the need for separate stimulus blocks for each electrolyzer stack. In various embodiments, sharing the stimulus generator is enabled by sequentially directing stimulus signals to different stacks. The resulting response signals, indicative of the impedance of cells or entire stacks, are processed locally at each respective electrolyzer stack. Advantageously, the stimulus generator may be remotely located, e.g., at a location that is subject to less stringent safety measures, thereby lowering both equipment and operational expenses.
