“…Platinum dissolution also causes Pt to migrate from the cathode into the membrane where it forms a Pt band [19]. Figure 34, a comparison of the Pt in the membrane content of the field operated stacks and those tested in the lab, again shows very little difference however in agreement with the slightly lower ECSA loss, the Pt in the membrane is also slightly lower.…”

This review summarizes the background and recent status of the fuel cell electric bus (FCEB) demonstration projects in North America and Europe. Key performance metrics include accumulated miles, availability, fuel economy, fuel cost, roadcalls, and hydrogen fueling. The state-of-the-art technology used in today's fuel cell bus is highlighted. Existing hydrogen infrastructure for refueling is described. The article also presents the challenges encountered in these projects, the experiences learned, as well as current and future performance targets.

“…The average current between the oxidation and reduction currents at 0.4 V represents a sweep rate of 0 mV s À1 , which will only be influenced by the hydrogen crossover. Cheng et al used this method to determine the hydrogen crossover of cells subjected to accelerated stress tests [17].…”

Although extensive research has been conducted, understanding the exact phenomena occurring during the operation of polymer electrolyte fuel cells (PEFCs) remains difficult. This research attempted to identify new reasons for the reduced performance of PEFC using an imaging technique. To begin with, H+ and OH− indicator sensors, which display red, blue, and green values (RGB) using digital microscopes, are developed and attached to each electrode of a membrane electrode assembly to enable quantitative analysis of ion generation. The proposed reaction in the fuel cell can be confirmed, and various reactions occurring in the electrode can be examined using this approach. In particular, H+ is generated at the anode and cathode of the anion exchange membrane fuel cell, which is found to be a major cause of performance deterioration.
