Abstract
The aim of the research is to offer an advantageous alternative at zero or negligible level of accident risks, of a solution of autonomy extended to electric vehicles by the installation of an embedded assembly composed of a reactor that produces hydrogen interconnected with a fuel cell. Hydrogen production will be obtained in a reactor by adding aluminum pieces in water catalyzed by sodium hydroxide and the electrical energy to be fed into the vehicle battery will be obtained from this gas when inserted into a Proton-exchange membrane fuel cells (PEMFC). Although, the chemical reaction between aluminum and alkaline solution is strongly exothermic, the gas produced is flammable and permeable in metals, and the chemical agents and residues involved in the process have considerable toxicity. This represents risks to vehicle users, to the environmental conditions where the vehicle will travel and the fire possibility. The extended autonomy proposal to receive approval in the continued manufacturing project of the electrical vehicles, a complementary Risk Management Project (RMP) has become decisive. For this reason, it was found an methodology that has innovative characteristics, such as the conceptualization of what is risk, the technical conducts to the risks identification, those that aim to neutralize or eliminate the identified risks and still, other very interesting that, from the identified risks, it is possible to elaborate a Training Matrix, a PPE Adoption Plan and a Preventive Maintenance Plan. The research will be developed through zero-order mathematical simulations to determine optimal design and operation parameters for the best possible performance with zero risk or at least acceptable level. The study will start from the zero condition of the system, when the yield of electricity production will be evaluated. At same time, considering the risks identified in the operation of the system a Risk Management Project (RMS) will be developed to neutralize or to minimize and to control the risks. Once defined, these actions will be implemented in the system and a new round of tests will be performed and the new results will be compared with the initial condition. Identifying differences, adjustments both in the operating conditions of the system and in the guidelines of the RMP should be made and new and subsequent starts of tests should be performed until the ideal condition of energy production with at least acceptable risk is obtained. In an innovative way, a RMP will be conceived within a technical development project of a device of relevance to the automotive industry, in order to offer acceptable conditions of risks to users, the environment and fire.
