Model Calculation of Energy Carriers Expenses on the Basis of Biogas in System Reformer - Fuel Cell for Autonomous Power Supply Systems

Abstract:

This paper presents the results of experiments and calculations of the energy expenses in tandem system reformer - fuel cell on hydrogenous fuel derived from biogas. Possibility of electricity generation based on complex use of organic and hydrogenous fuel at creation of objects of distributive systems of power supply will approach energy sources to the consumer, having increased energy-economic indicators and efficiency of fuel use. A promising direction in the creation of autonomous power supply systems in low-rise residential development is the use of fuel cells running on hydrogenous fuel derived from biogas Expenses of hydrogen fuel to operate the power installation with a predetermined capacity comparable with the required amount of hydrogen obtained by electrolysis. The calculated value of the efficiency of the system reformer - fuel cell, based on data on the required quantity of biogas and methane, as well as numerical characteristics of workflows fuel system, equal to 38.4%, confirms the relatively high efficiency of the use of hydrogenous fuel for the tasks of autonomous power supply. Usage of relatively low-cost hydrogen-containing fuel obtained from biogas from local secondary renewable resources will contribute to the creation of autonomous economic systems of power supply.
