Embodiment 1

[0128] Example 1 - Overview of Fuel Cells

[0129] and figure 1 Compared with the conventional fuel cell shown in a, the fuel cell according to the embodiment of the present invention is found in figure 1 b and figure 1 c. The fuel cell of the present invention comprises a conductive body comprising a composite material comprising at least one n-type and / or p-type semiconducting metal oxide and at least one ion-conducting material ( figure 1 b). The conductive body includes a first end face and a second end face for current collection. Set one end in contact with oxygen (O) and the second end for current collectors in contact with hydrogen (H 2 )touch. Such as figure 1 As shown in c, the conductive body of the fuel cell of the present disclosure may comprise a second composite material. Then, if figure 1 As shown in c, only the outermost end face is set to be connected to oxygen and H respectively 2 touch.

[0137] Materials and Preparation

[0138] Ionically Conductive Materials:

[0139] i) SDC (samarium-doped ceria), GDC (gadolinium-doped ceria) and YSZ (yttrium-stabilized zirconia) oxygen ion conductors were from Seattle Specialty Ceramics (Seattle, Washington, USA).

[0140] ii)) Synthesis of nanostructured SDC-Na by co-precipitation method 2 CO 3 , the nanocomposite electrolyte. In the synthesis of ceria-carbonate composites, the following chemicals were used in 1.0M solution: Ce(NO 3 ) 3 ·6H 2 O (Sigma-Aldrich) and Sm (NO 3 ) 3 ·6H 2 O (Sigma-Aldrich). Sm(NO 3 ) 3 ·6H 2 O solution and Ce(NO 3 ) 3 ·6H 2 The solution of O was mixed to the desired molar ratio. In order to achieve metal ions: the molar ratio of carbonate ions is 1:2, an appropriate amount of Na 2 CO 3 The solution (1.0M) was added slowly (10ml / min) to complete the wet chemical co-precipitation process of the ceria-carbonate composite. A mixture of...

Description

technical field [0001] This application relates to the field of fuel cells and their products. Background technique [0002] A fuel cell is a device that converts the chemical energy of a fuel and an oxidant (air or oxygen) into electricity. A fuel cell structure typically consists of a fuel electrode (anode) and an oxidant electrode (cathode) separated by an ion-conducting electrolyte membrane. Oxygen passes through one electrode and hydrogen passes through the other, producing electricity, water, and sometimes heat. At the anode, hydrogen and its electrons are separated so that hydrogen ions (protons) pass through the electrode while electrons are directed through an external circuit as direct current (DC). This current can provide power to useful devices. Hydrogen ions combine with oxygen at the cathode and recombine with electrons to form water. [0003] Conventional fuel cell technology typically requires three functional components: a porous anode, a dense and gas-...
