Abstract
Methods and systems may provide for technology to detect an unbalanced degradation among a plurality of fuel cells in an automotive system and apply an unbalanced control across the plurality of fuel cells based on the unbalanced degradation. In one example, the unbalanced control balances the degradation among the plurality of fuel cells.
Claims20
An automotive system comprising:
- a plurality of fuel cells;
- and
- a controller coupled to the plurality of fuel cells, the controller including a stored set of instructions, which when executed by the controller, cause the controller to:
- detect an unbalanced degradation among the plurality of fuel cells, and
- apply an unbalanced control across the plurality of fuel cells based on the unbalanced degradation.
2 more elements
At least one computer readable storage medium comprising a set of instructions, which when executed by an automotive system, cause the automotive system to:
- detect an unbalanced degradation among a plurality of fuel cells in the automotive system;
- and
- apply an unbalanced control across the plurality of fuel cells based on the unbalanced degradation.
A method comprising:
- detecting an unbalanced degradation among a plurality of fuel cells in an automotive system;
