Abstract: The present disclosure relates to systems and methods of detecting a hydrogen leak in a system comprising a hydrogen storage system storing hydrogen, a temperature sensor, a pressure sensor, a hydrogen storage system controller, and a notification system. The hydrogen storage system controller is configured to measure thermodynamic properties of the hydrogen in the hydrogen storage system, and the thermodynamic properties of the hydrogen are used to determine if there is a hydrogen leak in the fuel cell system. The notification system alerts a user of any detected hydrogen leak.

Abstract: A method for processing material includes sintering a portion of a sheet of material at a location on the sheet, moving the sintering location along the sheet of material at a first rate, and pulling the sintered material away from the sintering location at a second rate that is greater than the first rate.
