Overview

Fuel cells efficiently convert energy stored in fuel into electricity. Based on NTT's own technology, cells (i.e., power-generation elements) and a laminated “stack” for housing them were developed. Moreover, in cooperation with the outside world, a fuel-cell system featuring the world's highest power-generation efficiency and lifetime was developed. These technologies contribute to reduction of CO2 emission.

Features

  • Ceramic cells that enable high- efficiently power generation
  • Original electrode material that realizes longer lifetime
  • Original stack configuration that draws out best cell performance
  • Even higher efficiency by utilizing high-temperature exhaust heat

Application scenarios

  • Power can be supplied to telecommunications buildings and offices at high efficiency (low CO2-emission output level)
  • Simultaneous supply of heat and power to schools and restaurants
