Methods, apparatuses, and computer program products for diagnosing a degradation condition in an electrolyzer

An apparatus for diagnosing a degradation condition in an electrolyzer, the apparatus comprising at least one processor and at least one non-transitory memory comprising program code, wherein the at least one non-transitory memory and the program code are configured to, with the at least one processor, cause the apparatus to at least:

• receive data corresponding to a plurality of operational parameters of an electrolyzer stack, the plurality of operational parameters comprising at least an input voltage and an operational current;
• generate one or more runtime current-voltage (I-V) curves based on the input voltage and the operational current;
• compare the one or more generated I-V curves to one or more expected I-V curves;
• identify a first set of one or more degradation conditions based on one or more deviations between the one or more generated I-V curves and the one or more expected I-V curves;
• identify one or more data clusters of operational parameter data corresponding to one or more times the electrolyzer operated with one or more operational parameters in an undesirable range;
• identify a second set of one or more degradation conditions based on the one or more identified data clusters;
• compare the first set of one or more degradation conditions and the second set of one or more degradation conditions to identify if one or more degradation conditions are present in both the first set of one or more degradation conditions and the second set of one or more degradation conditions;
• and,
• if one or more degradation conditions are present in both the first set of one or more degradation conditions and the second set of one or more degradation conditions, report the one or more degradation conditions that are present in both the first set of one or more degradation conditions and the second set of one or more degradation conditions.

A computer program product for diagnosing a degradation condition in an electrolyzer, the computer program product comprising at least one non-transitory computer-readable storage medium having computer-readable program code portions stored therein, the computer-readable program code portions comprising an executable portion configured to:

• receive data corresponding to a plurality of operational parameters of an electrolyzer stack, the plurality of operational parameters comprising at least an input voltage and an operational current;
• generate one or more runtime current-voltage (I-V) curves based on the input voltage and the operational current;
• compare the one or more generated I-V curves to one or more expected I-V curves;
• identify a first set of one or more degradation conditions based on one or more deviations between the one or more generated I-V curves and the one or more expected I-V curves;
• identify one or more data clusters of operational parameter data corresponding to one or more times the electrolyzer operated with one or more operational parameters in an undesirable range;
• identify a second set of one or more degradation conditions based on the one or more identified data clusters;
• compare the first set of one or more degradation conditions and the second set of one or more degradation conditions to identify if one or more degradation conditions are present in both the first set of one or more degradation conditions and the second set of one or more degradation conditions;
• and,
• if one or more degradation conditions are present in both the first set of one or more degradation conditions and the second set of one or more degradation conditions, report the one or more degradation conditions that are present in both the first set of one or more degradation conditions and the second set of one or more degradation conditions.
