Michael Marr
Research
Mike’s research is on using the relatively new process of suspension plasma spraying to deposit YSZ electrolyte coatings in metal-supported SOFCs. For good performance, the electrolyte should be thin and dense and have low gas permeability. With plasma spraying, achieving these properties is challenging because the coatings inherently contain pores and cracks.
Mike is studying the effects of numerous process parameters on the properties of the resulting electrolyte coatings. The most promising electrolytes are then deposited in full SOFCs for electrochemical testing. Mike is also conducting general studies on suspension plasma spraying to better understand why certain pore and crack features form in the coatings. As a result of all of this research, electrolyte performance has steadily improved.
