Fuel cell electric vehicles (FCEVs) use hydrogen as fuel and exhaust only water. They provide driving ranges and fueling times comparable to gasoline vehicles. Despite the advantages, FCEVs have been in and out of spot light of the auto industry for the past several decades. The information on the development of fuel cell vehicles by major automakers is disparate. This report systematically examined the technical developments of FCEVs since the introduction of the first lab-based fuel cell vehicle in 1966. It included an overview of 117 FCEV models from 31 automakers. It should help the stakeholders to gain an insight …

Fuel Cell Electric Vehicles (FCEVs) can provide customers with the benefits of low to zero greenhouse gas emissions, high performance, and comfort without compromising range and refill time. With three major automakers (Honda, Hyundai, and Toyota) planning to introduce consumer FCEVs by the end of 2015, FCEVs will play an increasingly important role in the electric vehicle arena. Building hydrogen fueling infrastructure has been identified as a major obstacle in FCEV commercialization. This report is part of an ongoing effort within an Electric Vehicle Transportation Center (EVTC) project: "Fuel Cell Vehicle Technologies, Infrastructure and Requirements." This report is based on …

Computational Fluid Dynamics Simulation Of United Launch Alliance Delta Iv Hydrogen Plume Mitigation Strategies, Stephen Guimond
Electronic Theses and Dissertations
During the launch sequence of the United Launch Alliance Delta IV launch vehicle, large amounts of pure hydrogen are introduced into the launch table and ignited by Radial-Outward-Firing-Igniters (ROFIs). This ignition results in a significant flame, or plume, that rises upwards out of the launch table due to buoyancy. The presence of the plume causes increased and unwanted heat loads on the surface of the vehicle. A proposed solution is to add a series of fans and structures to the existing launch table configuration that are designed to inject ambient air in the immediate vicinity of the launch vehicle's nozzles …
