    • An electrochemical device, such as a fuel cell, and method of forming it, in which electrodes, such as anode and cathode, are disposed on a semipermeable or permeable membrane having ion conduction channels. Electrocatalyst is deposited on locations on the electrodes limited to and corresponding to the ion conduction channels. In a first embodiment, anode and cathode electrodes sandwich the membrane, a counter electrode is connected to one of the electrodes, electrolyte containing an electrochemical precursor to the electrocatalyst is applied to the other electrode whereby, upon applying current to the counter electrode, electrocatalyst is deposited on locations on the first electrode corresponding to the ion conduction channels. The process is repeated with the counter electrode connected on the other electrode of the cell. In a second embodiment, a combination of a first electrode and a first membrane is assembled as is a combination of a second electrode and a second membrane. A counter electrode and electrolyte containing an electrochemical precursor to the electrocatalyst are separately applied to the first combination, then the second combination whereby, upon applying current to the counter electrodes, electrocatalyst is deposited on locations on the first and second electrodes corresponding to the ion conduction channels. The surfaces of the first and second membranes are joined opposite their respective electrodes to a porous coupling layer to form the electrochemical device.
    • 诸如燃料电池的电化学装置及其形成方法,其中诸如阳极和阴极的电极设置在具有离子传导通道的半透膜或可渗透膜上。 电催化剂沉积在限定于并对应于离子传导通道的电极上的位置上。 在第一实施例中,阳极和阴极电极夹住膜,对电极连接到一个电极,将包含电催化剂的电化学前体的电解质施加到另一个电极,由此,在向对电极施加电流时,电催化剂为 沉积在对应于离子传导通道的第一电极上的位置上。 重复该过程,反电极连接在电池的另一个电极上。 在第二实施例中,第一电极和第一膜的组合如第二电极和第二膜的组合一样被组装。 将含有电催化剂的电化学前体的对电极和电解质分别施加到第一组合,然后第二组合,由此,在向对置电极施加电流时,电极催化剂沉积在对应于离子传导的第一和第二电极上的位置 通道。 第一和第二膜的表面与其各自的电极相对接合到多孔耦合层以形成电化学装置。

    • In a method of converting alkanes to their corresponding alcohols, ethers, olefins, and other hydrocarbons, a vessel comprises a hollow, unsegregated interior defined first, second, and third zones. In a first embodiment of the invention oxygen reacts with metal halide in the first zone to provide gaseous halide; halide reacts with the alkane in the second zone to form alkyl halide; and the alkyl halide reacts with metal oxide in the third zone to form a hydrocarbon corresponding to the original alkane. Metal halide from the third zone is transported through the vessel to the first zone and metal oxide from the first zone is recycled to the third zone. A second embodiment of the invention differs from the first embodiment in that metal oxide is transported through the vessel from the first zone to the third zone and metal halide is recycled from the third zone to the first zone. In a third embodiment of the invention the flow of gases through the vessel is reversed to convert the metal oxide back to metal halide and to convert the metal halide back to the metal oxide.
    • 在将烷烃转化成其相应的醇,醚,烯烃和其它烃的方法中,容器包括中空的未分离的内部限定的第一,第二和第三区域。 在本发明的第一实施方案中,氧与第一区中的金属卤化物反应以提供气态卤化物; 卤化物与第二区中的烷烃反应形成烷基卤; 并且烷基卤与第三区中的金属氧化物反应以形成对应于原始烷烃的烃。 来自第三区域的金属卤化物通过容器输送到第一区域,并且来自第一区域的金属氧化物被再循环到第三区域。 本发明的第二实施例与第一实施例的不同之处在于金属氧化物通过容器从第一区传送到第三区,金属卤化物从第三区再循环到第一区。 在本发明的第三个实施方案中,反过来通过容器的气体流将金属氧化物转换回金属卤化物并将金属卤化物转化回金属氧化物。
