Do Fuel cells work in space?

SOFCs are being considered for power generation and for use in space because of their high efficiency, high power density, and extremely low pollution. They have an all-solid construction and can operate at high temperatures–producing clean, efficient power from easy-to-transport fuels instead of pure hydrogen.

When were fuel cells first used in space?

First invented in 1839 by Welsh scientist William Robert Grove, the fuel cell wasn’t commercially used until the 1960s. As part of Project Gemini — which took part from 1962-1966 — NASA used fuel cells to generate power for probes, satellites and space capsules.

How much hydrogen is in space?

After months of careful checks and tests, the number they found was 0.127 particles per cubic centimeter, or about 120 hydrogen atoms in a space the size of a quart of milk.

How cold is interstellar space?

The average temperature of outer space near Earth is 283.32 kelvins (10.17 degrees Celsius or 50.3 degrees Fahrenheit). In empty, interstellar space, the temperature is just 3 kelvins, not much above absolute zero, which is the coldest anything can ever get.

Is interstellar space hot or cold?

And on the other side of the boundary, the interstellar medium is at least 54,000 degrees Fahrenheit, which is hotter than expected. However, this plasma is so thin and diffuse, the average temperature around the Voyager probes remains extremely cold.

Is there oxygen on space?

In space, there is very little breathable oxygen. This prevents the oxygen atoms from joining together to form oxygen molecules. That’s why astronauts need to wear a spacesuit when they are outside the spacecraft.

Can u cry in space?

Astronauts can’t cry the same in space as they do on Earth. Your eyes make tears but they stick as a liquid ball. In fact, they sting a bit. So — space tears don’t shed.” So in space, you can actually watch a ball of your tears float around.
