Abstract
Fuel cells having an efficient means of thermal insulation such that all of the components requiring high temperature operation are contained within a single housing and whereby such thermal insulation is disposed exterior to such housing.
Claims8
A method of regulating operation of a solid oxide fuel cell, comprising:
- forming a substantially isothermal reaction zone,
- converting fuel to hydrogen and by-products within the substantially isothermal reaction zone at a reaction temperature within a reaction temperature range,
- converting the by-products to exhaust products and thermal energy within the substantially isothermal reaction zone,
- maintaining the reaction temperature range, and
- employing thermal energy from converting the by-products to assist in maintaining the reaction temperature range, further comprising terminating converting fuel when the reaction temperature is outside the reaction temperature range.
