# Fuel Cells (FUEL)

[Home](./index.md)

## Parts Catalog

These modules are an alternative to solar panels, also offering way better weight and endurance than batteries.

### Fuel Cell Specifications

#### Specification Spreadsheet (WIP)

aim is 42 hours of runtime using only internal fuels. (which is seven kerbal days (six hours per day))

151,200 seconds of runtime (see runtime sheet)
