In-Situ Electrolyte Replenishment for Long Fuel Cell Life. Phase II Final Report

PDF Version Also Available for Download.

Description

The carbonate fuel cell has many advantages over conventional methods of producing electricity. It converts hydrocarbon fuels directly into electricity with a high efficiency (>70% in a co-generation plant configuration) and consequently releases less carbon dioxide greenhouse gases (>30% less compared to a combined cycle gas turbine plant). Its adaptability to meet the customers' specific power requirements is ideally suited for distributed power generation. The advantages of distributed power generation include site flexibility, fuel source flexibility, less capital investment risk and elimination of transmission and distribution investments. The fuel cell becomes economically competitive if its life exceeds 40,000h. The current ... continued below

The carbonate fuel cell has many advantages over conventional methods of producing electricity. It converts hydrocarbon fuels directly into electricity with a high efficiency (>70% in a co-generation plant configuration) and consequently releases less carbon dioxide greenhouse gases (>30% less compared to a combined cycle gas turbine plant). Its adaptability to meet the customers' specific power requirements is ideally suited for distributed power generation. The advantages of distributed power generation include site flexibility, fuel source flexibility, less capital investment risk and elimination of transmission and distribution investments. The fuel cell becomes economically competitive if its life exceeds 40,000h. The current predicted lifetime of the central cells of a stack is 44,000h, based on electrolyte inventory considerations. Methods of extending fuel cell life even further are being sought to enhance its commercial competitiveness.
