N2 - Surface transportation in Mexico City contributes to pollutant gas emissions, favoring the occurrence of respiratory diseases in the inhabitants while also causing the increase of greenhouse gases in the atmosphere. This study evaluates the use of a bus fleet powered by fuel cells, for sustainable development of public transport in the city. Three types of buses in four main routes of public transport in Mexico City are compared to determine their characteristics of required power and energy, fuel consumption and pollutant emissions. Simulations are performed using driving cycles, technical specifications of buses based on real data collected by bus operators, technical specifications and technical reports of the city's government. Results show that the Insurgentes and Eje Central routes have the highest fuel consumption and thus emit a higher concentration of toxic gases, compared to the other routes. It is also concluded that there are numerous operational, environmental and economic benefits of fuel cell electric buses (FCEB) over traditional diesel or diesel hybrid buses. The most important benefit would be the reduction of fuel consumption and, hence, gas emissions by 37 % over the bus with diesel engine and 30 % compared to diesel hybrid bus. If hydrogen cell buses were implemented, Insurgentes and Tepalcates routes would have a hydrogen consumption of 14.4kg/100km, while Tláhuac and Eje Central one of 9kg/100km. Finally, the main difficulties for implementing the FCEB are analyzed.
