Tubular electrochemical cell

Abstract

The present teachings relate to an electrochemical cell having a closed Fermat spiral shape. The electrochemical cell comprises an anode, a cathode, an electrolyte, a fuel channel, an oxidant channel, and optionally a reforming layer. The electrochemical cell can be made through extrusion, gel-casting, or 3-D printing. The electrochemical cell can be a solid oxide fuel cell.

Description

technical field [0001] The present invention relates to tubular chemical cells. Background technique [0002] Electrochemical devices (such as fuel cells, oxygen pumps, sensors, etc.) often offer the opportunity to efficiently convert chemical energy into electrical energy with minimal pollution. Electrochemical devices typically include electrochemical cells that can be implemented in planar, tubular or monolithic designs. Various designs have various disadvantages, such as slow start-up of planar solid oxide fuel cells ("SOFCs") and lower volumetric power densities of tubular SOFCs. [0003] Although tubular battery designs have demonstrated sufficient thermal shock resistance as well as high mechanical strength, they can have low volumetric power packing densities relative to other battery designs. For example, to produce an equivalent amount of power, tubular electrochemical cells are typically much larger in size than planar or monolithic electrochemical cells. One d...
