What is the purpose of a reformer in a fuel cell system? To provide a hydrogen-rich gas to the fuel cell stack To limit particulate discharge to the atmosphere To permit the fuel cell stack to produce an alternating current output To reduce the amount of cooling water needed A phosphoric acid fuel cell (PAFC) uses hydrogen as a fuel and is to be connected ft the electrical grid. Indicate the primary required components of such a fuel cell. What is the geothermal resource used by most existing geothermal (non ground-source heat pump) systems? Geopressurized Magma Hydrothermal EGS What is syn gas? A mixture of CH_4 and CO_2 (methane and carbon dioxide). 55-70 percent methane A flammable gas mixture containing CO, H_2, CH_4, N_2, CO_2, and higher hydrates Chemically modified vegetable oils suitable for diesel fuel A mixture of CO and H_2 (carbon monoxide and hydrogen)
