# Electrochemical engineering
## MicroSim spec
- **Recommended sim type:** circuit/flow
- **Microsimmability score:** 74/100
- **Layout:** drawing region (canvas) on top; control region (sliders/buttons) below.
### Parameters (tunable controls)
- `Cell voltage / overpotential - 0 to 3 V`
- `Current density - 0 to 1000 A/m^2`
- `Electrolyte concentration`
### What animates
Ions migrate between electrodes and a current-versus-[[Voltage|voltage]] (polarization) curve traces out as voltage and concentration change, with reaction rate tied to current.
### Learning objective
Connect cell current and reaction rate to applied voltage and concentration.

## Concept summary
Electrochemical engineering designs cells and reactors where electrical current drives chemical change, as in electrolysis, electroplating, and flow batteries.
## Build checklist
- [ ] Claim it: set `status: in-progress` + `lease` + `leased_at`
- [ ] Write the child page explaining the concept (tie it back to process engineering)
- [ ] Finalize parameter ranges and defaults
- [ ] Implement the p5.js sketch (drawing + control regions)
- [ ] Add caption + the learning objective on the page
- [ ] Set `status: done`
## p5.js sketch
```javascript
// MicroSim: Electrochemical engineering
let controls = {};
function setup() {
// createCanvas(...); create sliders for the parameters above.
}
function draw() {
// background(...); read controls; render circuit/flow; respond live.
}
```
