Automating the reversible fuel cell

Combining and automating conventional fuel cell and electrolyzer technologies has the potential to free us from fossil fuels.

1505 LearnedLessons

Plants convert sunshine into energy sources (glucose, cellulose) while exhausting oxygen. The reversible fuel cell is similar. The regular fuel cell is an electrochemical device that converts the chemical energy of a fuel (without combustion) into electricity. A reversible fuel cell (RFC) operates in two directions. In its "reverse" mode, it generates hydrogen from electricity and water, while in the "forward" mode it generates electricity from hydrogen. For the past decade, I've been writing and talking (including on TV1) about the need for fully developing the automated RFC. This means mass production of an inexpensive device that can convert intermittent energy forms…

Experts weigh in on distillation plant measurement problems

Bela Liptak and his crew tell how to resolve difficulties with measuring column differential pressure and flows of flare and natural gas.

Question: I always use your valuable books in my field as a control & instrumentation engineer. I have three questions, and if you could help me it will be so appreciated: 1) Installation differential pressure transmitters on tall towers (inlet and outlet) for vapor service has been a big…
