1. Infra-estrutura para uso energetico do hidrogenio : estações de abastecimento para veiculos com celulas a combustivel / Infrastructure for hydrogen energy use : fuelling stations for fuel cell vehicles
In this work it was made a study about electrolytic hydrogen production in fuelling stations for supplying a hypothetical fleet of fuel cell vehicles in São Paulo city. A lightweight fleet projection for the year 2020 in São Paulo city was made. Based on the estimative fleet, the number of vehicles using fuel cells and able to be refueled on these fueling

2. Preparation of Pt, W e Os binary and tertiary alloys for the oxidation of methanol in low temperatures fuel cells / Preparação de ligas binárias e ternárias de Pt, W e Os para a oxidação de metanol em células a combustível de baixa temperatura
Modern society integrally depends on the production and consumption of energy for its activities like cooking, lighting and transportation and also for industrial processes. The increase in the demand for energy increases the levels of pollution, which has a direct negative effect in human health. Thus, it is imperative to search for new power sources which,

3. Impacts on the environment and on the consumption of fuels due to the introduction of a light fuel cell vehicle fleet in São Paulo City-SP / Impactos ambientais e na matriz de consumo de combustiveis pela introdução de uma frota de veiculos leves com celulas a combustivel na cidade de São Paulo - SP
Percebe-se, atualmente, em todo o mundo, que as grandes cidades enfrentam problemas de poluição do ar derivados do crescimento do tráfego de veículos urbanos. Este aumento no número de veículos além de ocasionar um maior consumo de combustíveis de origem fóssil (não renovável), também é responsável pela emissão de vários poluentes que impacta

4. Eletrocatálise e poluição ambiental
This work considers mainly the problem of environmental pollution due to the production of energy by burning fossil fuels, particularly in urban vehicles. Electrochemical energy conversion is proposed as a partial solution to this problem, through the use of hydrogen in fuel cells. In both the production of hydrogen by electrolysis and in the electrochemical

5. Veiculo eletrico com sistema energetico hibrido : Celula de combustivel/baterias eletroquimicas
Zero emission vehicles are indicated as an ideal solution to minimize the environment problems at the large urban cities. At the present only the electric vehicles hold at this category. To viability this kind of vehicle must be defined the energy supply. The most used energy often are the batteries, but the advanced technology of this kind of system limits
