The　operational　performance　of　proton　exchange　membrane　fuel　cells　(PEMFC)　is　highly　influenced　by　temperature,　making　effective　thermal　management　essential.　However,　the　multivariate　coupling　between　pumps　and　radiators　presents　significant　control　challenges.　To　address　this　issue,　a　dual　DDPG-PID　control　strategy　is　proposed,　integrating　temperature　and　flow　rate　variations　to　enhance　system　stability　and　response.　Simulation　results　demonstrate　that　the　proposed　method　significantly　reduces　temperature　control　errors　and　improves　response　time　compared　to　conventional　PID-based　strategies.　Specifically,　the　D-DDPG　PID　achieves　a　temperature　error　reduction　of　up　to　75.4%　and　shortens　the　average　tuning　time　by　up　to　25.6%　compared　to　PSO-PID.　Furthermore,　the　strategy　optimizes　cooling　system　performance,　demonstrating　its　effectiveness　in　PEMFC　thermal　management.　©　2025　by　the　authors.
