New electrolyte highway enables low-temperature hydrogen fuel cells

Posted on by

[…]Researchers at Kyushu University in Japan have developed a new type of solid-oxide fuel cell (SOFC) that operates at 300℃ (500°F) , a notable reduction from typical operating temperatures. “The team expects that their new findings will lead to the development of low-cost, low-temperature SOFCs and greatly accelerate the practical application of these devices,” said the researchers in a press release

….

Such heat requires costly, specialized heat-resistant materials, making the technology expensive for many applications. A lower operating temperature is expected to reduce these manufacturing costs

….

The implications of this work extend beyond this specific fuel cell. The design principle of creating efficient ion pathways in materials provides a basis for developing other energy technologies.Professor Yamazaki suggests the same concept could be applied to improve other tools for decarbonization. “Beyond fuel cells, the same principle can be applied to other technologies, such as low-temperature electrolyzes, hydrogen pumps, and reactors that convert CO₂ into valuable chemicals, thereby multiplying the impact of decarbonization,” he highlighted.

You Can Now Tell Google Which Websites You Prefer in Search Results

[…]If you frequently test features with Google Labs, you might remember trying this one out: Preferred Sources, as the name implies, lets you tell Google which websites you prefer to read news from. The goal, then, is to see pages from those sites in future Google searches about news stories, assuming those sites publish content related to your search.

Here’s how it works: When you search for something covered in the news, Google will display a “Top stories” section at the top of the search results page. While you can simply browse the stories that Google curates for you, you can also now click a new button to the right of the “Top stories” title. From here, you can search for any website, and click a checkbox next to its name to save it to your list of preferred sources.

[…]

Now, you can refresh your search results, which, with any luck, will populate with more of the sources you added to this list. Not only will they appear more frequently in the “Top stories” section going forward, Google may offer you a new “From your sources” section as well, which should only contain the websites you’ve added to your list.
