    • A digital file may be stored on a storage device and deleted upon reading of the file. In one example, at least a portion of the stored file may be read, such as by a processor. In response to the reading of the stored file, at least part of the at least a portion of the stored file that has been read may be deleted. In further examples, the at least part of the at least a portion of the stored file may be deleted progressively while the stored file is being read, after a triggering event, or after a delay in time. According to another example, a user may provide an indication representative of the at least part of the at least a portion of the stored file that is to be deleted after the at least a portion of the stored file is read.
    • 数字文件可以存储在存储设备上,并且在读取文件时被删除。 在一个示例中,存储文件的至少一部分可以被诸如处理器读取。 响应于存储的文件的读取,可以删除已经读取的所存储的文件的至少一部分的至少一部分。 在另外的例子中,存储文件的至少一部分的至少一部分可以在存储的文件正被读取之后,在触发事件之后,或者在时间延迟之后逐渐删除。 根据另一示例,用户可以在读取所存储的文件的至少一部分之后提供代表所存储文件的至少部分的待删除的至少部分的指示。

    • A method comprises creating an electrode by depositing alternating first and second layers on a substrate, and using the electrode to make a solid oxide fuel cell. The first layer comprises a metal, and the second layer comprises a non-metal, for example a ceramic material. The substrate may be moved between a first region containing the metal and substantially free of the non-metal, and a second region containing the non-metal and substantially free of the metal. The composition of the metal and/or the non-metal may be varied along the thickness of the layers. The deposited layers may be heated. A fuel cell may have a fuel cell electrode that comprises a substrate, and alternating first and second layers deposited on the substrate, where the first layer includes a metal and the second layer includes a non-metal. The fuel cell may be a solid oxide fuel cell.
    • 一种方法包括通过在衬底上沉积交替的第一和第二层来形成电极,并且使用电极制备固体氧化物燃料电池。 第一层包括金属,第二层包括非金属,例如陶瓷材料。 衬底可以在包含金属的第一区域和基本上不含非金属之间移动,以及包含非金属并且基本上不含金属的第二区域。 金属和/或非金属的组成可以沿层的厚度变化。 沉积的层可以被加热。 燃料电池可以具有包括衬底的燃料电池电极和沉积在衬底上的交替的第一和第二层,其中第一层包括金属,第二层包括非金属。 燃料电池可以是固体氧化物燃料电池。
