In alkaline, the Pt/C catalyst after high-potential cycling shows a decrease of double-layer capacitance over time because of carbon layer dissolution. Whereas, low-potential cycling in acid shows less ORR activity loss, mainly caused by Pt Ostwald ripening, and does not lead to a significant change in double-layer capacitance. Physicochemical results indicate that carbon surface oxides are formed after high-potential cycling in acid causing an increase in the double-layer capacitance and severe ORR activity loss due to Pt poisoning. Herein, we perform a study of platinum-carbon (Pt/C) degradation mechanisms using potential cycling of accelerated durability testing protocols in acidic and alkaline media.

There are testable success criteria for each guideline. WCAG 2.0 contains 12 guidelines organized under 4 principles: Perceivable, Operable, Understandable, and Robust (POUR for short). This certifies it as a stable and referenceable technical standard.

WCAG 2.0 is also an international standard, ISO 40500. The iGovPhil Project officially adopts the Web Content Accessibility Guidelines (WCAG 2.0) as the accessibility standard for all its related web development and services.
