A new stochastic algorithm for proton exchange membrane fuel cell stack design optimization

► Develops a new, original algorithm for PEM fuel cell stack design optimization. ► Solves a PEMFC problem that is analytically intractable and computationally hard. ► Outperforms three state-of-the-art methods on three performance metrics. ► Claims of improved results are statistically validated. ► A Markov chain analysis of the algorithm is provided.
