Electrolysis temperature control

Abstract

A method of controlling the temperature of an inlet fluid of at least one electrolyser cell stack. The at least one electrolyser cell stack comprising at least one fluid inlet for the inlet fluid and at least one fluid outlet for an outlet fluid, the method comprising: predicting, based on a model, an outlet fluid temperature a desired operating condition; and setting an inlet fluid temperature setpoint based on the predicted outlet fluid temperature; the method further comprising: receiving a measurement of the temperature of the outlet fluid; determining an delta between the predicted outlet fluid temperature and the measurement of the outlet fluid temperature; and inputting a correcting parameter into the model based on said determined delta.
