Fuel cell - Wikipedia, the free encyclopedia - StumbleUpon Demonstration model of a direct-methanol fuel cell. The actual fuel cell stack is the layered cube shape in the center of the image Scheme of a proton-conducting fuel cell The first fuel cells were invented in 1838. There are many types of fuel cells, but they all consist of an anode, a cathode and an electrolyte that allows charges to move between the two sides of the fuel cell. The fuel cell market is growing, and Pike Research has estimated that the stationary fuel cell market will reach 50 GW by 2020.[3] History[edit] Sketch of William Grove's 1839 fuel cell The first references to hydrogen fuel cells appeared in 1838. In 1939, British engineer Francis Thomas Bacon successfully developed a 5 kW stationary fuel cell. Types of fuel cells; design[edit] Fuel cells come in many varieties; however, they all work in the same general manner. At the anode a catalyst oxidizes the fuel, usually hydrogen, turning the fuel into a positively charged ion and a negatively charged electron. SOFC[edit]

The Anatomy of a Perfect Landing Page - Formstack - StumbleUpon Placement and Content 7. Keep It Above the Fold The space a visitor sees without having to scroll is where the most important parts of the webpage should be. 8. Optimize a landing page for conversion over time. 9. Implementing motivational speeches, videos of user testimonials, and product images into a home page can have a positive impact on viewers, as well as give shoppers an extra push to look further into a product. Bellroy uses great imagery and videos on many of their pages. 10. Links connecting the user to a bunch of other sites or pages will distract them and have a negative impact on conversions. This landing page is designed well, but look at all those header links getting in the way of the message!
