Abstract
The present invention relates to a balance of plant (BOP) system of solid oxide fuel cells including a burner, a reformer, a steam generator, and heat exchangers, wherein the burner, the reformer and the steam generator are laid sequentially on top of each other to transmit the flames and burned gas generated from the burner directly to the reformer and the steam generator disposed sequentially on top of the burner, and the heat exchangers introduce the flue gas discharged from the steam generator thereinto and preheat the process air to be supplied to cathodes of stacks.

A balance of plant (BOP) system of solid oxide fuel cells comprising a burner, a reformer, a steam generator, and heat exchangers, wherein the burner, the reformer and the steam generator are laid sequentially on top of each other to transmit the flames and burned gas generated from the burner directly to the reformer and the steam generator disposed sequentially on top of the burner, and the heat exchangers introduce the flue gas discharged from the steam generator thereinto and preheat the process air to be supplied to cathodes of stacks.
A solid oxide fuel cell stack module comprising stacks, a burner, a reformer, a steam generator, and heat exchangers, wherein the burner, the reformer and the steam generator are laid sequentially on top of each other to transmit the flames and burned gas generated from the burner directly to the reformer and the steam generator disposed sequentially on top of the burner and the heat exchangers introduce the flue gas discharged from the steam generator thereinto and preheat the process air to be supplied to cathodes of the stacks.
A method for operating solid oxide fuel cells comprising:
- the heating step of laying a burner, a reformer, and a steam generator sequentially on top of each other to transmit the flames and burned gas generated from the burner directly to the reformer and the steam generator disposed sequentially on top of the burner;
- and
- the preheating step of introducing the flue gas discharged from the steam generator into heat exchangers to preheat the process air to be supplied to cathodes of stacks.
