English title:	Application of high-power impulse magnetron sputtering thin films to enhance the durability of carbon coatings in metallic bipolar plates for hydrogen fuel cells and electrolyzer
Spanish title:	Aplicaci�n de pel�culas delgadas de pulverizaci�n cat�dica de magnetr�n de impulso de alta potencia para mejorar la durabilidad de los recubrimientos de carbono en placas bipolares met�licas para celdas de combustible de hidr�geno y electrolizadores
English abstract:	Metallic bipolar plates are a promising candidate to replace conventional graphite metallic bipolar plates due to higher power density and lower costs in proton exchange membrane fuel cells. However, great challenges still exist for the application of metallic bipolar plates since they are working in an acidic, humid, warm, and polarized environment that reduces the lifetime of metallic bipolar plates. The application of coatings is essential to enhance interfacial conductivity and corrosion resistance. In this study, four different metal-doped amorphous carbon coatings (a-C:Cr, a-C:W, a-C:Nb and a-C:Ti) have been deposited by bipolar high-power impulse magnetron sputtering on stainless steel. The influence of high-power impulse magnetron sputtering parameters on the coating-substrate interface, as well as the coating properties have been evaluated with the purpose of evaluating their potential application in proton exchange membrane fuel cells.
Spanish abstract:	Las placas met�licas bipolares son un candidato prometedor para el remplazo de placas convencionales de grafito debido a la densidad de alta potencia y bajo coste de las celdas de combustibles de membrana de intercambio de protones (PEM). Sin embargo, existen a�n grandes retos para la aplicaci�n de la placas met�licas bipolares debido a que han de funcionar en un ambiente �cido, h�medo y a temperatura que reducen la vida �til de las actuales placas convencionales. La aplicaci�n de recubrimientos es esencial para mejorar la conductividad interfacial y la resistencia a la corrosi�n. En este estudio, cuatro tipos diferentes de carbono amorfo dopado con metal (a-C:Cr, a-C:W, a-C:Nb and a-C:Ti) han sido depositados y caracterizados para su potencial aplicaci�n.
