## Description

This MCP server provides specialized tools for electrochemical analysis. It allows AI agents to calculate activation overpotential using `calculate_activation_overpotential`, determine mass transport limitations with `calculate_concentration_overpotential`, and compute total voltage losses via `calculate_total_overpotential`. It also includes `calculate_ohmic_loss` to account for internal resistance in electrochemical cells.

## Tools

### calculate_concentration_overpotential
Calculates the concentration overpotential due to mass transport limitations

### calculate_activation_overpotential
Calculates the activation overpotential using the Tafel approximation

### calculate_total_overpotential
Calculates the total voltage loss including kinetic, mass transport, and resistive components

### calculate_ohmic_loss
Calculates the ohmic loss due to internal resistance

## Frequently Asked Questions

**What is activation overpotential?**
It is the voltage required to overcome the energy barrier for the charge transfer reaction at the electrode surface.

**How do I calculate total voltage loss?**
You can use the `calculate_total_overpotential` tool by providing the individual activation, concentration, and ohmic loss values.

**Does this tool account for ohmic losses?**
Yes, the `calculate_ohmic_loss` tool specifically calculates voltage drops caused by the internal resistance of cell components.
