San Mao (English pen name Echo), a famous wandering female writer from Taiwan, China, has influenced the growth of several generations of Chinese people, especially Chinese women, with her works and life experiences. Taking the English version of San Mao’s most famous work, Stories of the Sahara, as an example, this paper analyzes the English version, especially the translator Mike Fu's representation of San Mao's female image. The article holds that San Mao, as a narrator, bystander and witness of Saharan life, has a rich personal image, which is influenced by both eastern culture and western culture. Translator Mike Fu insists on "faithfulness" and has androgynous translation consciousness, which successfully reproduces the image of San Mao. Through the foreign translation platforms of China literature, such as Paper-Republic, and the promotion of foreign mainstream medias, the English version has gained more readers and comments, and San Mao has formed an irreplaceable female image through the understanding of different readers.

Fuel cells are made from fuel and oxygen. Because of its low pollution, high energy conversion efficiency and high reliability, fuel cell has become the future direction of new energy application, the technological development path in the field of fuel cell research has great significance to the development of technological and energy innovation. Using the patent analysis method, this paper analyses the patent data from Derwent Innovation Index quantitively to study the state of application for patents, core technologies, highly cited patents and the main patentees. It shows that auxiliary device and related methods were a research hotspot in recent years; as the biggest patent holder of fuel cell technologies, Toyota, Honda motor Co. and Nissan motor Co. have an advantage. This paper has discovered some potential problems behind the phenomena and some suggestions are put forward finally.
