System and method for electrochemical cell system and leak detection and indication

摘要

An electrochemical cell system is provided having: at least one electrochemical cell stack, each stack having at least one reactant fluid inlet; a pressure transmitter arranged in the at least one reactant fluid inlet of each stack; and a control unit for regulating the electrochemical cell system, the control unit receiving at least one signal value from the pressure transmitter indicative of the reactant fluid pressure. The control unit may compare the at least one signal value with a stored values and generate a leak indication based on the rate of pressure decay within the electrochemical cell system. A method of detecting and indicating a leak is also disclosed.

1. An electrochemical cell system comprising:
a) at least one electrochemical cell stack, each stack having a reactant fluid inlet; b) a pressure transmitter arranged in the reactant fluid inlet of each stack; and c) a control unit for regulating the electrochemical cell system, the control unit receiving a signal value from the pressure transmitter indicative of the reactant fluid pressure and comparing the signal value with a stored value, wherein the signal value and the stored value correspond with pressure in the at least one electrochemical cell stack at a pre-set time period after initiating shut-down of the electrochemical cell system.
